How do you rehydrate underglaze?
Can I rehydrate my glaze if it is dried out? Yes, just add water and give it a little while to hydrate and then stir. Once mixed to smooth consistency it is ready to use again. It is ideal to run it through a screen or sieve, but not required.
How do you thicken underglaze?

The more surface area exposed to air, the quicker it will dry and thicken.
Can you add water to glazes?
Glaze should be stirred often, as contents can settle during use. If the glaze thickens over time, you can usually just add water.
Can Underglazes be mixed?
Unlike glazes, underglaze colors can always be mixed together to create new colors. Also unlike glazes, the color when fired is similar to the color when wet (another reason why painters often prefer underglazes.) However, a final consideration with underglazes has to do with firing temperatures.
How do you fix dry underglaze?
Break up the chunks first and you will have an easier time of it but yes, completely dried out or partially dried out glaze can be revived. If it’s store bought in one of those little bottles add a tablespoon of hot water at a time and shake and stir. You may need to sieve it again as well.
Can clay mold?
It is incredibly common for mold to grow on clay as it is a natural material. Different types of mold can grow on different types of clay, and many different variants will determine what type of mold grows. Often clay that has been left for a very long time will have developed some mold on it.
How do you get an underglaze stamp?
To make the sponge “stamp pad,” slowly pour a dollop of underglaze onto the center of the sponge. 2. Using any brush you have on hand, blend the under-glaze dollop into the sponge until it is fully absorbed, creating a ceramic stamp pad. Use this area for “inking” your stamps.
How do you make underglaze ink?

Is underglaze the same as slip?
The main difference in slips and underglazes is the texture. Underglazes don’t have a texture or thickness as they contain less amount of clay. Colored slips, however, do leave behind texture and some thickness because they contain more clay.
What consistency should underglaze be?
Underglaze Consistency The water content impacts the concentration of materials (specific gravity), which can affect the opacity and saturation of the color. So, it’s good to take notes about thinness or thickness of your underglazes when mixing.
Do 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.
How do you use underglaze powder?
Mix 100g powdered underglaze colour and 25mls water to double cream consistency and apply to bisque. Underglaze powders can be applied to greenware by mixing 100g powder with 140g water.
