Huel Pottery - Functional Stoneware, with various glazes that we have formulated, all of which are lead-free and safe to use in the oven or microwave. Functional Ware is available in Skeena blue, Northern Lights and indigo glazes. The website contains only a portion of the various stoneware pieces that are available at our Kispiox Valley gallery. The Skeena blue and Northern Lights glazes use local clay from the Kispiox and Skeena rivers as their base ingredient and add their unique characteristics to the glazes.
