One of my duties at the studio is to measure and combine the dry ingredients for glazes before hydrating them. The unfired glazes are almost never the same color as the finished product, but some of the ingredients are truly beautiful! Almost all the ingredients are a shade of white other than the colorants, although the textures vary widely- from powdered sugar(ferro frit) to sparkling white sand(spodumene)! The bright green and pink seen here are copper and cobalt carbonate, being mixed to make the color Variegated Blue. Isn’t chemistry cool!?
