Glaze finish is not a style choice you make after picking a color. It is a chemical outcome of the flux-to-silica ratio in the formula. Change the ratio and you change the entire surface. Matte glazes scatter light. Glossy glazes reflect it. Satin glazes do both. Crystalline glazes grow actual crystals during cooling. Each finish…

Majolica glaze is not just another pottery finish. It is a tin-opacified white surface that transforms porous earthenware into a luminous canvas for brush decoration at temperatures between cone 06 and cone 04 (1828-1940°F / 998-1060°C). The tin oxide suspended in the glaze blocks light transmission through the glass layer, creating an opaque white ground…

What Are Natural Slips and How Do They Work as Glaze? Natural slip is liquid clay, nothing more. It is the same clay body you throw or handbuild with, thinned with water to a creamy consistency and applied to the surface of your pot. When fired to the clay body’s maturation temperature, the slip vitrifies…

Terra sigillata is not a glaze. It is a super-refined clay slip that produces a soft satin sheen without any glass-forming materials. That distinction matters because terra sigillata does not melt in the kiln. It bonds to the clay surface through physical adhesion of microscopic clay platelets, not through vitrification. This guide covers every step…

Ceramic glaze is not paint. It is a glass coating whose final color depends on exact chemistry, precise firing conditions, and consistent application technique across every single piece. You open the kiln after a 12-hour firing. The mugs you glazed as a matching set come out as three different shades of blue. This problem has…

Most potters assume commercial glazes cost more than mixing their own. The truth depends entirely on how many pots you make each year and which glaze materials you buy in bulk. By the Numbers Commercial vs Studio-Mixed Glazes: Key Figures Sources: Ceramic Arts Network community survey data, manufacturer pricing, and studio cost tracking $12-$45 Cost…
