About US

Seattle Pottery Supply was founded by Jim and Sue Lunz in March of 1975, when they recognized the need for a quality supplier of pottery-related products and services to the growing Pacific Northwest ceramics community. In 1981, Seattle Pottery Supply added custom clay and glaze formulation, firing services, kiln manufacturing, kiln service, and even more specialized products and learning materials to its product list.

Since that time, Seattle Pottery Supply has provided its ever-broadening supply of pottery-related products and services to an increasingly longer list of satisfied artists, potters, ceramics enthusiasts, production studios, schools, universities, and other educational institutions. 

In August of 2019, SPS was purchased by three friends, Dylan Ambauen, Dave Enslow, and Dhruv Agarwal, who saw the chance to preserve and grow an iconic Seattle arts community landmark. Under the new management, SPS has focused on expanding its reach across the country with a robust online catalog and a focus on top-notch customer service and a knowledgeable, helpful staff.

Our flagship Seattle store is located at 35 S Hanford St in Seattle's SODO district.
