Firing converts ceramic work from weak clay into a strong durable crystalline glasslike form. The goal of bisque firing is to convert greenware to a durable semi vitrified porous stage where it can be safely handled during the glazing and decorating process. For earthenware such as fired clay pottery to hold liquid it needs a glaze. Using glazes requires a lot of experimentation and practice.

If the temperature goes too high the glaze will become too melted and run off the surface of the pottery. Terms used in ceramics.

Ceramic glaze definition is a mixture of powdered materials that often includes a premelted glass made into a slip and applied to a ceramic body by spraying or dipping and capable of fusing to glassy coating when dried and fired.

For success a potter must know the correct temperature range at which their glaze becomes mature. Many factors like the kind of kiln or the kind of clay you use impact the final result.
