Over a Century of American-Made Art Supplies
AMACO — the American Art Clay Company — has produced ceramic and craft supplies at its Indianapolis, Indiana factory since 1919. For more than a century, the company has supplied schools, universities, professional studios, and home crafters with clays, glazes, and underglazes made in the same city where the company was founded. AMACO's longevity in American manufacturing is rare; most art supply companies have shifted production overseas over the past four decades, but AMACO has maintained its Indianapolis roots through generations of ownership changes and market shifts.
The company's product range covers the full ceramic workflow: air dry clays for hand-building without a kiln, earthenware and stoneware firing bodies for functional pottery, underglazes for applying color to raw and bisque clay, and glazes for final surface treatment. The breadth of the line means that an art teacher outfitting a classroom, a college ceramics studio setting up production wheels, and a home hobbyist building their first pinch pots can all source their supplies from a single American manufacturer.
Clay and Glaze Product Lines
AMACO's air dry clay line is the entry point for most buyers — non-toxic formulas in white, terra cotta, and gray that dry hard without kiln firing. The Stonex line is self-hardening and produces a particularly durable finished piece; the standard air dry is more economical for large classroom volumes. Both are formulated to accept acrylic paint and other surface treatments once dry.
For potters working with kilns, the Velvet Underglaze line is AMACO's best-known product. The Velvet series offers 60+ colors in semi-translucent formulas that fire from cone 05 through cone 10, covering low-fire, mid-fire, and high-fire kilns. The Teacher's Palette glaze line is formulated specifically for classroom use — reliable, opaque, and consistent from firing to firing. The Potter's Choice high-fire glaze series offers more complex visual effects appropriate for functional pottery.
Art Education and AMACO
AMACO has supplied art education programs across the United States for over a century and has a particularly deep relationship with K-12 art teachers. The company offers classroom packs sized for school use, technical support for educators setting up ceramic programs, and curriculum resources that accompany their products. This commitment to education is part of what has sustained AMACO's American manufacturing — educational institutions often require domestic sourcing for budget and policy reasons, and AMACO's Indianapolis production meets those requirements.
For buyers choosing between AMACO and other ceramic supply brands: AMACO's advantage is the integration of their product lines. An AMACO underglaze applied over AMACO clay and fired with AMACO-recommended timing is a tested combination. The company has done the formulation work to ensure their products are compatible from raw clay through final glaze firing.
