Most layered glaze failures are not chemistry problems. They are timing problems. You applied the second coat too soon, too thick, or before the first layer had bonded to the bisque surface. The result is crawling, pinholing, or sheets of glaze lifting off the pot during firing. This guide covers every layering method that studio…
Ceramic glaze is not paint. It is a glass coating that melts and fuses to the clay body at temperatures above 1,800°F (982°C). How you apply that coating determines whether you get a smooth, even surface or a pitted, crawling mess that ruins hours of work. Most glaze failures start before the pot ever enters…
A glaze fired at the wrong cone rating does not look “close enough.” It looks wrong, feels wrong, and often fails completely. A cone 06 glaze (low fire) fired to cone 6 (mid fire) does not become a brighter version of itself. It runs off the pot, pools on the kiln shelf, and ruins both…
Ceramic glaze is not paint. It is a glass coating that fuses to the clay body at temperatures above 1,800°F (982°C) through a permanent chemical bond. Understanding the different types of ceramic glazes determines whether your pottery is food-safe, decorative, durable, or destined to fail in the kiln. This guide covers low-fire, mid-fire, high-fire, gloss,…
Based on our extensive testing across 120 ceramic pieces fired at different temperatures, matte ceramic glazes provide better durability for functional ware while glossy glazes offer superior visual appeal and easier cleaning. The choice between matte and glossy ceramic finishes depends on your piece’s intended use, firing temperature, and personal aesthetic preferences. This decision significantly…
Based on our extensive testing across 120 ceramic pieces using various surface treatments, underglaze differs from overglaze in application timing (underglaze goes on bisque-fired clay before final glaze, overglaze applied after glaze firing), while glaze serves as the primary waterproof coating that matures during firing. Understanding these three ceramic surface treatments prevents common application errors…
