chinese landscape painting
created by some of China's most highly respected artists in Sichuan. These paintings clearly resemble the technique and brushstrokes exercised by ancient masters. Artists of traditional Chinese painting do not attempt to disguise the contemporary Chinese artist's interpretation of a classical subject matter, but aim to reflect the artistic accomplishment of the old master. Through the process of studying old masterpieces, our artists of traditional Chinese painting perpetuate the most important values in classical Chinese art.
Methods and Styles in Chinese Landscape Painting
In landscape art Xieyi predominates. It allows the feelings to flow, encourages the freedom of expression that makes the artist. It conveys an imagery unconstrained by reality, unlimited by the conventional view of a subject. Proportion, perspective and light are viewed as limitations and dealt with accordingly. The viewer is expected to move his eyes as he takes in the full scene, absorbing the detail from minutely different angles, using the imagination as well as other senses.
Most early Chinese painters were also poets and calligraphers, and their works included aspects of those disciplines. The Chinese see painting, poetry and calligraphy as interlinking art forms. Colophons (inscriptions) have historically been a common feature of Chinese landscape art - adding information, sentiment and decoration.
Chinese landscape painting developed two separate styles known as blue and green and ink and wash. Blue and green uses bright, primary colour pigments to create a rich and striking work that is visually attractive. Ink and wash by contrast uses dark shades right through to black, to produce an intense impression of the artist’s personal conception of his subject.
The painting itself is a product of the imagination as much as it is a representation of place. The focus is invariably on peace and tranquillity, expressed idealistically according to what the artist sees. The result can be vague to the untrained eye, but equally evokes an appreciation of something other-worldly, a temporary escape from reality.
Some Famous Chinese Landscape Artists
An early painter to introduce the styles and techniques for which Chinese landscape art would become famous was Dong Yuan (c934 – c962). His best-known work is perhaps The Xiao and Xiang Rivers.
During the Yuan Dynasty Wu Zhen (1280 – 1354) and others further developed the less realistic, more imaginative expression in the work they were doing. Wu Zhen’s The Central Mountain shows his distinctive style.

sandcasting with pewter
WHAT IS PEWTER?
Pewter is a malleable metal alloy, traditionally 85-99% tin, with the remainder consisting of copper, antimony, bismuth and lead. Copper and antimony act as hardeners while lead is common in the lower grades of pewter, which have a bluish tint. It has a low melting point, around 170–230 °C, depending on the exact mixture of metals. The word pewter is probably a variation of the word spelter, a colloquial name for zinc. Pewter was first used around the beginning of the Bronze Age in the Near East. The earliest piece of pewter found is from an Egyptian tomb from 1450 BC.
A typical European casting alloy contained 94% tin, 1% copper, and 5% antimony. A European pewter sheet would contain 92% tin, 2% copper, and 6% antimony. Asian pewter, produced mostly in Malaysia, Singapore, and Thailand, contains a higher percentage of tin, usually 97.5% tin, 1% copper, and 1.5% antimony. This makes the alloy slightly softer.
WHAT DOES PEWTER GET CAST INTO?
Pewter is an alloy of tin that has been gracing homes for more than 3500 years. The Egyptian civilisation, the Roman Empire and mediaeval Europe all appreciated its qualities. Today's pewter maintains its soft shine and represents an environmentally sound metal that is wholly appropriate for the use of contemporary artists.
Modern British pewter is an alloy of tin (92%), antimony (6%) and copper (2%), sometimes referred to as Britannia Metal. Because it is lead-free, it keeps its bright shine and is non-toxic. Some old pewter develops a grey patina and has a metallic smell due to its lead content. In the 14th Century, because pewter could be worked so easily, it largely replaced wood, pottery, stone and leather as the main material for the making of domestic items. Furthermore, worn out pewter items could be recycled.
The Worshipful Company of Pewterers was set up to control the quality of pewter and the trade became of great economic importance. This situation lasted until the start of the 19th Century when fine china, glass and stainless steel became available in large quantities. Craftsmen today use techniques such as casting, spinning, hammering and chasing to produce a range of decorative products for use in the home or the office, often to celebrate important events.
About Sandcasting
Sand casting is used to make large parts (typically Iron, but also Bronze, Brass, Aluminum). Molten metal is poured into a mold cavity formed out of sand (natural or synthetic).
Petrobond sandThis is fine sand that has been mulled with an oil based binding agent called Petrobond. Because it has no water, there is no steam- and while some gases are liberated from the oil, I haven't found venting to be necessary. The sand has a somewhat oily texture and smells bad after it has been burnt by the molten metal- but it works well and eliminates some trickiness from the casting process. The sand closest to the molten metal will be burnt to black dry sand after casting. This used sand can be blended back into the mix or can be scraped away (as best as you are able) and discarded. Unburnt sand can be used again

Pat Steir
Pat Steir applying a soap ground, San Francisco 1993
Pat Steir: Drawing Out of Line concentrates on five distinct bodies of work: minimal and intimate word/image drawings (1971–74); richly delineated serial investigations of line (1975–76); heroically scaled wave drawings (1983–86); four interrelated series of stunning waterfall drawings (1991);
San Francisco Waterfall I, 1991

84 3/4" x 60"
and a new and dramatic series featuring broad, dark gestural marks that sometimes serve as a backdrop for delicate pastel grids (2007–08). Wall drawings, an ongoing aspect of Steir’s work since 1977, are also represented in a re-creation of Self-Portrait: An Installation, first seen at the New Museum in New York in 1987. In addition to the wall drawing, the exhibition will include some 50 drawings on paper, dramatically varied in scale—from intimate, journal-like sheets to compositions up to 21 feet long—set in relationship to her paintings and prints. The exhibition will encompass 6,000 square feet of gallery space within the Chace Center.
"Her drawings resemble worksheets, filled with grids, diagrams, color charts, crosses, dashes, and crosshatching. They’re self-consciously about process, in other words: the very building blocks of art. But they have none of the dry rigor (blooming into bliss) of Sol LeWitt or Agnes Martin, two artists she clearly revered and whose work reflects similar interests. Instead they mingle minimalist restraint with the emotive effusions and scientific obsessions of more singular artists, from Leonardo da Vinci to Cy Twombly....
"The influence of artists such as LeWitt and Martin is quickly overtaken by Courbet, Hokusai, and the whole Asian tradition of ink painting. Steir dives in, embracing chance and spontaneity, as well as the idea that in painting a waterfall, the drips of ink and oil paint and the spatter of gold powder she uses might all actually be the thing represented, not just imitations of it.
1991
The results of her paintings and prints have been likened to a variety of natural phenomena, waterfalls, sea mists, and stars, for example, that appear to emerge from the richly layered surfaces. Her works also evoke the underlying forces of the world around us and convey a meditative, poetic, and serene mood rather than a direct representation of external phenomena. No matter how one "reads" Pat Steir's work, the dynamic application of pigment and provocative surfaces she has created here have transformed the apse into a contemplative space and a portal into another world, be it the primal forces of nature and the cosmos or an interior world of personal thought and reflection.

Casting using concrete or wax or jesmonite
CASTING USING CONCRETE
You can make all kinds of objects out of concrete. They will be heavy, but this can be an advantage when you want to construct something that is durable -- especially for outdoor use. You can cast your own paving stones, sculptures, wall hangings, feet, water feature basins, rocks and more. Here are some basics on how to cast different concrete shapes.
To make shapes out of concrete you will want to build a form. The inside of the form will define the shape you are creating. Then when you fill your form with cement and let it harden you shake loose or break open the form and have your finished object set in solid concrete.
Do your design first. Sketch it out so you know how it will look. If you are making a form for a single use, like the bowl for a small water feature, for example, you can construct it out of materials that can be broken away later. If whatever you are pouring in concrete will have layers of texture applied, you don't have to be fussy with the mold itself. You might want to simply use wood to create your form
Make a frame or form from rough materials like wood, or more exacting and detailed molds from foam, plastic, silicone, urethanes bought from industrial suppliers or craft shops. You can even make a flat textural piece you can press into the surface of wet concrete like a mold-type stamp. There are also wonderful selections of pre-cast molds available to buy on the internet and in specialty stores
You will want to clean your mold before using it and, if it is a flexible mold, lightly oil the inside to keep the cement from sticking. (You can buy a lubricant or use 5W-30 motor oil.)
Mix your cement and pour it into your mold. Portland cement creates an nice smooth concrete but is less strong than mortar. Cement mixes work well, too. For fine work you may prefer to use plaster. If you are doing something small enough to move, pour in a quarter of the mixture at a time tapping or lightly shaking the mold to release air bubbles
Let the cement set for 24 hours and either break away a solid mold or shake out a flexible mold to release your creation
Chip clean any little unwanted pieces and coat it with texture, leave as is or paint your final product. In the end you will have a cast concrete shape you can have for practical use or decor!
Some artists who cast in concrete
Jennifer Cohen - USA
Sculptor graduate from Yale 2000
Grey Line in Six Parts (i) (2008)
Each work is an amalgamation of the static and the kinetic, with the depersonalized concrete structure segueing into the vividly suggestive flourish of the shoe or the glove. In Cohen’s work there is a clear separation between the body (as represented in the concrete structures) and the objects that adorn and embellish it. These objects are grafted onto the body, injecting the abstract form with a distinctly animate aspect. Yet the sense is less of political engagement than of uncanniness; Cohen’s work is unsettling precisely because of its lack of a clearly declared agenda.

Elizabeth White - USA
"Affiliations with conservation/educational organizations have matured my awareness of people's connections with nature. Desire for harmony with my surroundings prompted me to delve into the study of specialty paint techniques, trompe l'oeil and the practice of feng shui. My current sculptural works range from ephemeral to concrete in my use of natural and found objects, and cement. The commodity of human hair inspired the continuing series called "Renewable Resource". Fear of the irreversible pollution to the environment and our gene pool inspired the protest with the "Dirty Bomb" series."

sculpture
Presented by the Tate Collectors Forum 2003
Whiteread makes casts of carefully chosen objects, most of which bear the trace of human use. She casts the ‘negative’ spaces around or beneath these objects, which then become the ‘positive’ forms of the sculptures. In Untitled (Nine Tables), the artist takes a familiar item of furniture, but presents only the residue or memory of its presence. This evokes the past of the object as well as the lives of those who once used it. Whiteread has said: ‘I always use secondhand things, because there’s a history to them.
N.B. no to be confused with 'Concrete Art' - which is a term introduced by Van Doesburg in 1930 'Manifesto of Concrete Art' published in the first and only issue of magazine Art Concret. He called for a type of abstract art that would be entirely free of any basis in observed reality and that would have no symbolic implications. He stated that there was nothing more concrete or more real than a line, a colour, or a plane (a flat area of colour). The Swiss artist Max Bill later became the flag bearer for Concrete art organising the first international exhibition in Basle in 1944. He stated that the aim of Concrete art is to create 'in a visible and tangible form things which did not previously exist ¿ to represent abstract thoughts in a sensuous and tangible form'. In practice Concrete art is very close to Constructivism and there is a museum of Constructive and Concrete art in Zurich, Switzerland.

CASTING USING WAX/LOST WAX PROCESS
Lost-wax casting sometimes called by the French name of cire perdue (from the Latin cera perduta) is the process by which a brass or bronze sculpture is cast from an artist's sculpture; in industrial uses, the modern process is called investment casting. An ancient practice, the process today varies from foundry to foundry, but the steps which are usually used in casting small bronze sculptures in a modern bronze foundry are generally quite standardized.

CASTING USING JESMONITE
Although it has been around since the 80’s Jesmonite is a relatively little known material despite the fact it remains one of the only water-based resins around today. Jesmonite is made up of two components, a liquid acrylic compound that binds a gypsum powder (not unlike that used for plaster casting). The resulting mixture acts much like plaster for 24 hours or so then hardens to acrylic-like properties. It is ideal for covering large foam sculptures by itself or together with fibre-glass matting to add extra strength. Because it is a water based compound, all the protective equipment necessary when working with G.P resin and fibre-glass is not required. Although a dust mask and goggles are essential when mixing any powder or liquid. There are several types of Jesmonite already available and new developments released in 2008 included the introduction of metal finishes for cold metal casting. Because it is a water-based resin, it is also ideal for coating polystyrene sculptures and foam core furniture designs with a durable, exterior shell, which can be sanded painted or upholstered to meet the users needs.
On its own it is very strong, it’s even weather proof, much like the properties of plastic, yet when combined with fibre-glass matting it becomes extremely strong and highly durable. It is also impact and flame resistant.
It is very popular when making large or load bearing structures particularly when used with polystyrene block sculpture as a core. This keeps the weight to a minimum whilst not compromising on structural strength. It is also suitable for making children’s toys and interactive sculptures where conventional resin/fibre glass usage would not be suitable.
How do I use Jesmonite?
Jesmonite is supplied in two parts, a liquid and a powder, these are mixed at a ratio of between 2-3 parts powder to 1 part liquid. Digital scales are not necessary to measure this material.
1.Measure out an adequate amount of powder first and add the acrylic liquid at a ratio to suit your work. Remember, the more of the acrylic liquid produces a runnier liquid. Check with your technician what viscosity suits your work best before starting.
2.Once combined the powder and liquid begin to react quickly so do not delay mixing and application. I find using an electric whisk or similar for about 1-2 minutes is enough to ensure all the lumps of powder are gone and it is a smooth texture before applying.
3.The mixture can be applied by brush as a plastic coating or in conjunction with fibre-glass. It can also be poured as a solid or a hollow slip casting.
Tip: The more powder you add the thicker the material becomes. Handy for filling the bits you’ve missed. Also adding more liquid will thin the material, making it ideal for casting highly detailed surfaces.
4.After around 15-30 minutes the surface can be worked like plaster, which makes it a great choice for fabricating complicated one-off shapes quickly and easily. Over the next 24-48 hours, the jesmonite will gradually harden into a tough plastic like material that can be cut, shaped, sanded and painted.

CHRISTINE BORLAND
Borland's practice negotiates territories in art, ethics, medical humanities and bio-politics. She gathers her source material as a result of research time spent in medical and forensic institutions, observing and participating in their practices. Borland does not merely expose her findings within the gallery but creates deeply poetic works that reinvest the clinical data with a human dimension, introducing aesthetics and ambiguity to an arena dominated by function and objectivity. Her observations often raise unsettling questions simply by making visible an arena usually inaccessible to the public.
Given the sensitive nature of her work, Borland has devised a personal moral framework, analogous to the Code of Medical Ethics, which serves to inform her practice and her choice of materials. Borland trained at The Glasgow School of Art and University of Ulster, Belfast, she has since collaborated with the Medical Research Council's Social and Public Health Sciences Unit, the Medical School at Glasgow University and the Penninsula Medical School in Cornwall.
Cast From Nature - Glasgow Sculpture Studios - 2010 to March 2011
The work involves creating a cast of a man who died and was dissected in the 19th century. Over the next three months Christine and her assistant will painstakingly take moulds from the cast, which she found broken and dusty, in storage at Royal College of Surgeons.
The process of creating this figure can be watched live by the public. However they aren’t allowed into the room where Christine is working. Instead, they can watch two live video feeds from a nearby gallery – one showing a wide-angle shot of the room, with it’s stainless steel tables and equipment, the other showing an overhead shot of the body as they work on it, with scalpels, razors and clay.
The idea is to recreate the aloof, removed viewpoint that would have existed in the dissection theatres of 19th century.
This was also a challenge when it came to recording Christine at work. Instead of being in the room, I had to be next door, watching the action, and describing it – whilst a recorder I left in the room recorded them as they worked.
SPIRIT COLLECTION - April to May 2000 - New York (Sean Kelly Gallery)
In "Spirit Collection," Borland has expanded her discourse to include a hot topic -- genetic science -- that also happens to hit Borland close to home (She is from Scotland and it was a Scottish biotech firm that cloned Dolly the Sheep and cells for Millie the pig). Borland has also presented her work here with more care. This installation is both varied and engaging. Works include a video of an animated 19th-century drawing of a boy with Duchenne Muscular Dystrophy, a sculpture consisting of several sets of painted porcelain female pelvises paired with baby's heads in birth positions, photography of bioluminescent jellyfish, and a microscope revealing the quickly-multiplying HeLa gene.
The centerpiece of the exhibition, however, is the eponymously titled Spirit Collection (1999). Numerous vaccum-sealed teardrop-shaped glass containers hang overhead, each filled with a combination of ethyl alcohol, preservative and water, and each containing a leaf. The leaves themselves look unreal, for Borland has bleached them white in the manner of makers of Victorian bell jar curios. But they are very real.
When the artist was working with geneticists at the University of Glasgow, she saw a tree outside the window of the Genetics department -- an undistinguished tree, in a not very prime spot over by the car park. She was told that the tree was grown from the seed of a Plane tree in Kos, Greece, under which Hippocrates, the father of medicine, first taught his students. While the locals knew little of the circumstances of the Glasgow seedling (more information was proffered after Borland's exhibition of Spirit Collection last year in Dundee, Scotland), Hippocrates' original tree is a famous, revered, ancient monstrosity, propped up on all sides -- a place of pilgrimage.
Borland harvested some leaves from the tree, and here they are. The leaves are preserved to emphasize their piece-of-the-true-cross "sanctity" as actual genetic material. Cherishing their origin, Borland defies the culture of cloning. But Borland's presentation of the leaves of a tree's "family tree" -- white, weird, spooky, afloat in the solution in a Frankenstein way -- also suggests that she fears that originals are being rendered ghostly in the age of the clone. The piece functions then as a sort of "burning bush," which fills the mind with all sorts of questions about the ambiguities of life after DNA research.
Five Set Conversation Pieces (1998) includes five female pelvises molded from obstetric models. Porcelain babies' heads are set in different positions by the pubis bone, while the upper bones are painted like old "china trade" china with blue ships, islands and trees. In those old days "bone china" meant wares actually made with ground-up human bones.
Borland implies that the birth process is a weak link in the saga of genetic material -- some positions, in the time before widespread C sections, led to still births -- yet DNA lived on in the china. Just think -- you could clone your great granddad from an old teapot. Not really, but its just the kind of startling thought that Christine Borland stirs up in this provocative exhibition.

The Swiss artist Max Bill later became the flag bearer for Concrete art organising the first international exhibition in Basle in 1944. He stated that the aim of Concrete art is to create 'in a visible and tangible form things which did not previously exist ¿ to represent abstract thoughts in a sensuous and tangible form'. In practice Concrete art is very close to Constructivism and there is a museum of Constructive and Concrete art in Zurich, Switzerland.

CASTING USING WAX/LOST WAX PROCESS
Lost-wax casting sometimes called by the French name of cire perdue (from the Latin cera perduta) is the process by which a brass or bronze sculpture is cast from an artist's sculpture; in industrial uses, the modern process is called investment casting. An ancient practice, the process today varies from foundry to foundry, but the steps which are usually used in casting small bronze sculptures in a modern bronze foundry are generally quite standardized.

CASTING USING JESMONITE
Although it has been around since the 80’s Jesmonite is a relatively little known material despite the fact it remains one of the only water-based resins around today. Jesmonite is made up of two components, a liquid acrylic compound that binds a gypsum powder (not unlike that used for plaster casting). The resulting mixture acts much like plaster for 24 hours or so then hardens to acrylic-like properties. It is ideal for covering large foam sculptures by itself or together with fibre-glass matting to add extra strength. Because it is a water based compound, all the protective equipment necessary when working with G.P resin and fibre-glass is not required. Although a dust mask and goggles are essential when mixing any powder or liquid. There are several types of Jesmonite already available and new developments released in 2008 included the introduction of metal finishes for cold metal casting. Because it is a water-based resin, it is also ideal for coating polystyrene sculptures and foam core furniture designs with a durable, exterior shell, which can be sanded painted or upholstered to meet the users needs.
On its own it is very strong, it’s even weather proof, much like the properties of plastic, yet when combined with fibre-glass matting it becomes extremely strong and highly durable. It is also impact and flame resistant.
It is very popular when making large or load bearing structures particularly when used with polystyrene block sculpture as a core. This keeps the weight to a minimum whilst not compromising on structural strength. It is also suitable for making children’s toys and interactive sculptures where conventional resin/fibre glass usage would not be suitable.
How do I use Jesmonite?
Jesmonite is supplied in two parts, a liquid and a powder, these are mixed at a ratio of between 2-3 parts powder to 1 part liquid. Digital scales are not necessary to measure this material.
1.Measure out an adequate amount of powder first and add the acrylic liquid at a ratio to suit your work. Remember, the more of the acrylic liquid produces a runnier liquid. Check with your technician what viscosity suits your work best before starting.
2.Once combined the powder and liquid begin to react quickly so do not delay mixing and application. I find using an electric whisk or similar for about 1-2 minutes is enough to ensure all the lumps of powder are gone and it is a smooth texture before applying.
3.The mixture can be applied by brush as a plastic coating or in conjunction with fibre-glass. It can also be poured as a solid or a hollow slip casting.
Tip: The more powder you add the thicker the material becomes. Handy for filling the bits you’ve missed. Also adding more liquid will thin the material, making it ideal for casting highly detailed surfaces.
4.After around 15-30 minutes the surface can be worked like plaster, which makes it a great choice for fabricating complicated one-off shapes quickly and easily. Over the next 24-48 hours, the jesmonite will gradually harden into a tough plastic like material that can be cut, shaped, sanded and painted.

CHRISTINE BORLAND
Borland's practice negotiates territories in art, ethics, medical humanities and bio-politics. She gathers her source material as a result of research time spent in medical and forensic institutions, observing and participating in their practices. Borland does not merely expose her findings within the gallery but creates deeply poetic works that reinvest the clinical data with a human dimension, introducing aesthetics and ambiguity to an arena dominated by function and objectivity. Her observations often raise unsettling questions simply by making visible an arena usually inaccessible to the public.
Given the sensitive nature of her work, Borland has devised a personal moral framework, analogous to the Code of Medical Ethics, which serves to inform her practice and her choice of materials. Borland trained at The Glasgow School of Art and University of Ulster, Belfast, she has since collaborated with the Medical Research Council's Social and Public Health Sciences Unit, the Medical School at Glasgow University and the Penninsula Medical School in Cornwall.
Cast From Nature - Glasgow Sculpture Studios - 2010 to March 2011
The work involves creating a cast of a man who died and was dissected in the 19th century. Over the next three months Christine and her assistant will painstakingly take moulds from the cast, which she found broken and dusty, in storage at Royal College of Surgeons.
The process of creating this figure can be watched live by the public. However they aren’t allowed into the room where Christine is working. Instead, they can watch two live video feeds from a nearby gallery – one showing a wide-angle shot of the room, with it’s stainless steel tables and equipment, the other showing an overhead shot of the body as they work on it, with scalpels, razors and clay.
The idea is to recreate the aloof, removed viewpoint that would have existed in the dissection theatres of 19th century.
This was also a challenge when it came to recording Christine at work. Instead of being in the room, I had to be next door, watching the action, and describing it – whilst a recorder I left in the room recorded them as they worked.
SPIRIT COLLECTION - April to May 2000 - New York (Sean Kelly Gallery)
In "Spirit Collection," Borland has expanded her discourse to include a hot topic -- genetic science -- that also happens to hit Borland close to home (She is from Scotland and it was a Scottish biotech firm that cloned Dolly the Sheep and cells for Millie the pig). Borland has also presented her work here with more care. This installation is both varied and engaging. Works include a video of an animated 19th-century drawing of a boy with Duchenne Muscular Dystrophy, a sculpture consisting of several sets of painted porcelain female pelvises paired with baby's heads in birth positions, photography of bioluminescent jellyfish, and a microscope revealing the quickly-multiplying HeLa gene.
The centerpiece of the exhibition, however, is the eponymously titled Spirit Collection (1999). Numerous vaccum-sealed teardrop-shaped glass containers hang overhead, each filled with a combination of ethyl alcohol, preservative and water, and each containing a leaf. The leaves themselves look unreal, for Borland has bleached them white in the manner of makers of Victorian bell jar curios. But they are very real.
When the artist was working with geneticists at the University of Glasgow, she saw a tree outside the window of the Genetics department -- an undistinguished tree, in a not very prime spot over by the car park. She was told that the tree was grown from the seed of a Plane tree in Kos, Greece, under which Hippocrates, the father of medicine, first taught his students. While the locals knew little of the circumstances of the Glasgow seedling (more information was proffered after Borland's exhibition of Spirit Collection last year in Dundee, Scotland), Hippocrates' original tree is a famous, revered, ancient monstrosity, propped up on all sides -- a place of pilgrimage.
Borland harvested some leaves from the tree, and here they are. The leaves are preserved to emphasize their piece-of-the-true-cross "sanctity" as actual genetic material. Cherishing their origin, Borland defies the culture of cloning. But Borland's presentation of the leaves of a tree's "family tree" -- white, weird, spooky, afloat in the solution in a Frankenstein way -- also suggests that she fears that originals are being rendered ghostly in the age of the clone. The piece functions then as a sort of "burning bush," which fills the mind with all sorts of questions about the ambiguities of life after DNA research.
Five Set Conversation Pieces (1998) includes five female pelvises molded from obstetric models. Porcelain babies' heads are set in different positions by the pubis bone, while the upper bones are painted like old "china trade" china with blue ships, islands and trees. In those old days "bone china" meant wares actually made with ground-up human bones.
Borland implies that the birth process is a weak link in the saga of genetic material -- some positions, in the time before widespread C sections, led to still births -- yet DNA lived on in the china. Just think -- you could clone your great granddad from an old teapot. Not really, but its just the kind of startling thought that Christine Borland stirs up in this provocative exhibition.
