Clay Planet started in the 1970's as a business called Marshall Craft, by a kiln designer and inventor, Marshall Wicke.
In the 1980's the business was purchased by Bob Millavec, the name changed to Claymaker, and moved to N. 13th Street in San Jose CA. It was there the business expanded and the mass production of ceramic clay was begun.
On January 2003 Claymaker became Clay Planet, with new ownership and management.
The business was expanded and moved to a larger facility at 1775 Russell Avenue in Santa Clara, CA.
Since taking ownership and moving to our new location, we have:
  • Greatly expanded what the retail store offers in products.
  • Added a second delivery truck with liftgate for residential kiln delivery throughout the bay area.
  • Purchased and partnered with Phoenix Ceramic Supply in Santa Cruz CA.
  • Created several new exciting clay bodies, expanding our line of clays by 8 new clays in our first 5 years.
  • Purchased (Sherry's) Western Ceramic Supply in San Carlos, CA. We are now the sole manufacturer of Western Ceramic Glazes, with distributors throughout California and beyond.
  • Designed new glaze colors in high fire, mid fire, and raku.
  • Added on-site & in house repair services of electric & gas kilns, and pottery wheels.
  • We offer firing services where you can drop off greenware or bisque and get your pieces fired to low, mid, or high fire in our kilns!
  • Partnered with Olander Earthworks to produce and distribute Texture Spheres clay texturing tools line.
We look forward to a great future with you as our customer!
