How do you fully glaze ceramics?
In order to make your own ceramic glaze, simply mix a glaze powder with water. It is a relatively simple process.

Do ceramic glazes go bad?
Glazes do not ‘go bad’ with age but, because different ingredients tend to come out of suspension at different rates, it is critical that the batch or bottle be mixed thoroughly before each application. Single firing (glaze applied to greenware) is not recommended with today’s glazes.
What happens when you Refire ceramics?
Refiring can be an issue with the body and the glaze. The glaze materials, as a mix, were melted on the first firing and combined to form a glass. That glass will melt completely, and seal the body surface, at a much lower temperature than on the first firing.

How do you paint already fired ceramics?
Use oil-based ceramic paints or a ceramic paint designed for use on fired ceramics. Although the top layer of the glaze has been taken off, the remaining glaze will resist the application of new paint. Apply the paint as normal using a brush and layer up the paint in thin layers to get the best effect.
Can you glaze bisque twice?
