"Contemplative Pots" by Anne Stewart

Quiet, subtle, ethereal; such are the epithets frequently elicited by the crystalline glazed porcelain of American ceramist John Tilton.

It's no accident that John Tilton's work is often described in metaphysical terms, for he intends, by using porcelain forms and his matte crystalline glazes, to address and explore the subtle realms of existence, or, as he puts it - the 'macrocosm and microcosm'.

A mathematician with a Master's degree, Tilton was working on his qualifying exams for a PhD in Mathematics in 1969 when he realized his calling. He had been potting for about a year. Initially becoming interested in ceramics as a way to release tensions accumulated by his work in the high-intensity realm of graduate mathematics, he became consumed with his love of the material and the exhilaration of creating clay forms. He even installed a potter's wheel in his bedroom, for lack of another place to put it.

The abstract reasoning demanded by high-level mathematics soon paled alongside the immediacy and tactile actuality of working with clay. Leaving behind the mathematics program, he embarked on a journey into the realm of ceramics, receiving his MFA in Ceramics in 1972, and initiating a dialogue with clay that has never ended. He has worked in earthenware, raku, stoneware and porcelain, but his current work is entirely one-of-a-kind porcelain. 'I'm absorbed in creating pieces which appear to contain their own universes,' he says. 'As you look closer and closer into the pot and at the glaze, you see more and more; the glazes are even fascinating when viewed through a microscope.'

Surface texture is another important element in Tilton's work. Occasionally enriching the surface of pots with a swirl or dabs of slip, most of the time he prefers to allow his glazes to provide texture. Textural effects are rich and diverse, including a satin, almost shiny texture; a soft, skin-like one; a velvety, very matte texture; a hoarfrost-like texture, glimmering in a matte surface; and a dense, lava- like mass. 'I'm interested in surfaces that don't appear to be surfaces because of their depth, and in the way colour affects the pots.' he says.

With a matte crystalline-glaze palette that includes various shades of algae green, sage, light to dark blue-green, baby blue, beige, deep pink, shell pink, mauve, white and black as well as a copper-red Sang de Boeuf and a deep cobalt blue glaze, it seems almost inconceivable that Tilton is colour-blind. Though unable to see many of the subtle colour variations in his glazes, he does perceive differences in colour value more accurately than most people, and points out that the effects he finds most pleasing are also appreciated by others.

Although glaze application is painstaking and scientifically accurate, Tilton says he relinquishes control of his pieces once they are in the kiln. 'The pots I make are crisp, simple, contemporary forms with precise layers of glaze applied over one another. They are a balance of my desire for control and their ultimate surrender to the fire, a process which transforms each one in a unique way. Philosophically, my work has much in common with woodfired pottery. Balancing control and surrender is teaching me many lessons.'

Tilton employs a diverse range of forms to express his vision, all originating with the thrown vessel. Confessing a deep love for historical and traditional pottery, he says he finds inspiration in their 'mystery and beauty', adding, 'I'm not making traditional pots, but I acknowledge the debt I owe them.' One factor that Tilton's pieces and traditional pots share is their quality of endurance, a theme running throughout Tilton's work. 'It's important to me that the pieces are of enduring value and have meaning over the life of ceramics; that they're meaningful in an historic context.' he says. Perhaps the form he is most identified with is the open, shallow bowl, the interiors of which become transformed into otherworldly landscapes under Tilton's steerage. Inside these bowls, the glazes are allowed full expression and are free to run, pool and exhibit effects substantially different from those seen on the outside of the vessels. Common to all his forms is a feeling of compact spaciousness, the result of strategic throwing: 'making every movement count'. Because translucence is important to Tilton, a great deal of time is spent in the throwing and trimming of each pot. Even if the piece ends up being glazed with a dark, opaque finish, translucence of the clay remains and contributes in a positive way to the outcome of the piece.

Firing takes place in a kiln specially designed to cool slowly and radiate heat inward during the cooling process. Tilton's pieces are reduction fired to cone 10, often multiple times. Pieces can receive up to a dozen firings before the glaze surface achieves a depth that pleases him. Between firings, glazes may be sandblasted or ground down for special effects; new glazes or the same glaze may be applied to the fired surface; or the piece may be refired as is. Tilton nurtures his vision with hour-long meditations twice a day. Constantly striving for a kind of perfection that embodies spirit and precision, the discipline of meditation helps with the discipline of working with his pots. Feeling that his pots reflect a deep commitment and spiritual opening, he says, 'From the most basic standpoint, the pieces I make are about growth: how shape evolves through a series of strategic steps; how the glaze and other elements of the pot's fired surface reflect the growth process; and, finally, how my own spiritual growth affects and is affected by each piece. I'm trying to make the purest statement that I can: a statement about what is.'
