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…
Most glaze failures happen before a brush ever touches bisqueware. The decision between mixing your own glazes from raw powders and buying ready-made liquid formulations shapes your entire ceramic process, from cost structure to creative control. This guide covers the full decision framework for studio mixing versus commercial ready-made glazes at every firing range. It…
Ceramic glaze is not paint. It is a thin layer of glass fused to clay at temperatures above 1,800°F, and what goes into that glass determines whether your morning coffee stays in the mug or slowly leaches metals into your body. Most potters assume any glaze fired to the right cone is automatically safe to…
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…
