The salt glaze is an approach glaze. While other glazes are applied before firing, the salt glaze is created during firing.
Crystal glaze
Crystal glazes are glazes in which crystals grow in the glaze during the firing process. They are formed during the cooling process and solidify with the glaze.
Faience/Majolica
This genre of pottery was born out of a desire to copy the brilliant white porcelain that could not be made in Europe until the 18th century because of a lack of kaolin.
