Every ceramic glaze is glass, and glass needs exactly three raw materials to form: kaolin for stability, feldspar as the melting engine, and silica as the glass itself. Remove any one of the three and the batch fails in the kiln. Get the ratios right and you control gloss, durability, and fit at temperatures from…
Ceramic glaze is not paint. It is a thin layer of engineered glass built from powdered rock, melted onto clay at cone 6 (2232°F / 1222°C) or cone 10 (2345°F / 1286°C). Understanding ceramic glaze chemistry means learning three ratios and nine metal oxides. This guide explains silica glass formers, kaolin stabilizers, feldspar and carbonate…
Most failed pots do not fail on the wheel. They fail days later, when a poorly joined handle pulls a chip out of the wall or an untrimmed foot ring rocks the piece sideways on the table. Advanced wheel work is exactly the point where the learning curve punishes small oversights. This guide covers throwing…
Most pottery does not crack because you touched it wrong. It cracks because one zone of the clay dried and shrank faster than the zone next to it. Drying is a controlled race between water leaving the surface and water migrating out from the center, and this guide walks you through winning that race with…
Sgraffito is not painting. It is cutting through a colored slip layer to reveal the clay body beneath, and every line you carve becomes permanent the moment the kiln reaches cone 6 (2232°F / 1222°C). This guide covers sgraffito, slip trailing, mishima, wax resist, stamping, carving, mocha diffusion, underglaze application, and engobe mixing, with slip…
The best pottery gift is usually not the most expensive one. A $14 bag of clay will get used ten times more often than a fancy gadget that sits in a drawer. Potters and aspiring potters are practical makers, and they measure a gift by how much it helps them make something. If you are…
