Does ceramic bisque need to be fired.

For earthenware such as fired clay pottery to hold liquid it needs a glaze. It has to be fired before painting you do not have to glaze it and fire again. This is actually fired at a low temperature which means that it still has some extra firing in it. The unfired bisque is too soft to work with.

The porous quality of some bisque fired clay makes it perfect for glazing as it absorbs liquid well. A bisque firing also prepares the pottery for glazing. Ceramic work is typically fired twice. Glaze adheres to the bisque surface because the porous ceramic absorbs the water in which the glaze materials are suspended.

Firing converts ceramic work from weak clay into a strong durable crystalline glasslike form. This is actually fired at a low temperature which means that it still has some extra firing in it. You must start with prefired ceramics. Bisqueware is the term for pots that have been bisqued fired for the first time the pots may also be called biscuit ware.

Now bisque is often considered a true ceramic even though the clay body isn t fully matured. 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. It is bisque fired and then glaze fired. Ceramic glaze is an impervious layer or coating applied to bisqueware to color decorate or waterproof an item.

You can just paint and spray it with a clear coat of finish.
