Seattle Pottery Supply

Jim and Sue Lunz founded Seattle Pottery Supply in March 1975 to serve the Pacific Northwest ceramics community. In 1981, the business added clay and glaze formulation, firing, kiln manufacturing, and technical services. It now combines in-house production, a Seattle store, and an online catalog for artists, studios, and educational institutions.

Clays are organized by type and firing temperature, expressed through ceramic cones. There are stoneware, porcelain, raku, casting slip, and wet or dry clays, with house and other manufacturers’ products. The shrinkage and absorption chart compares material characteristics, an essential part of connecting clay, form, and firing.

Glazes and colors include house products, Amaco, Mayco, Coyote, and other brands. Categories distinguish low, mid, and high firing temperatures, alongside raku, lusters, effects, and underglaze decorations. Transfers, silkscreens, brushes, and application tools expand ways of working on a piece’s surface.

Seattle Pottery Supply kilns are manufactured in-house and share the catalog with other options. Parts, bricks, shelves, posts, ventilation, and cones accompany installation and use. Brent, Pacifica, and Shimpo wheels, alongside slab rollers, extruders, mixers, and wedging tables, equip home or professional studios.

The shop carries hand-building and wheel tools, knives, sponges, stamps, and rulers. Raw materials include feldspars, kaolins, oxides, stains, and other formulation ingredients. Accessories, from teapot handles to plaster molds, complete production details that a bag of clay alone does not address.

Services include firing pieces, kiln and wheel repair, technical inquiries, and raku workshops. The shop is at 35 S Hanford Street, Seattle, WA 98134, with separate retail and warehouse hours. Kiln buying guides, firing resources, and tutorials accompany equipment selection.

In 2019, Dylan Ambauen, Dave Enslow, and Dhruv Agarwal purchased the business and expanded its online reach. Seattle Pottery Supply maintains the connection between manufacturing and practical support: choose a clay, match it with a glaze, equip the studio, and arrange firing. That continuity defines a supplier serving both a first project and a studio’s ongoing work.
