How do you re-glaze and refire a ceramic piece?

To re-glaze and refire a ceramic piece, first, carefully clean the surface of the existing glaze to remove any dust or oils, then sand it lightly if necessary for better adhesion. Apply the new glaze evenly, ensuring it covers the entire surface you wish to refinish. Allow the glaze to dry completely before placing the piece in a kiln for firing, following the appropriate temperature and duration guidelines for the type of glaze and clay used. Once fired, let the piece cool down gradually to avoid thermal shock.

Depends on exactly what you mean ---- of course you cannot really remove the fired glaze and then apply another one but it is often possible to paint ceramic colours onto a fired item and then re-fire it. If its very old then there may be a problem with cracking of the pot or crazing of the glaze. In the end you just have to try it and hope for the best!

How does a glaze change the properties of a ceramic?

A glaze acts as a protective and decorative coating for ceramic surfaces. When applied and fired, it forms a glass-like layer that enhances durability, prevents moisture absorption, and adds a smooth, glossy finish. This transformation not only improves the ceramic’s appearance but also makes it more resistant to stains and scratches. At Astonishing Detail, we apply a similar concept with our ceramic coating services, creating a protective layer that keeps vehicles looking polished and well-protected.
