Can you add glaze before bisque firing?

What is the difference between underglaze and glaze?
Underglaze and glaze can both be used to decorate a piece of pottery. The difference is that underglaze is applied before a clear glaze. It is easier to use underglaze for intricate designs. However, a clear overglaze will seal the piece and make it non-porous.

When single firing pottery, you can glaze leather hard clay or bone dry clay. It’s best to experiment with the clay body and glaze you are using to see which works best for you. One of the risks of raw glazing is that the glaze can flake off the unfired pot. It can flake off bone dry and leather hard clay.
Can you put underglaze on Bisqueware?
Underglaze on Bisqueware Many commercial underglazes are made to work on greenware and bisqueware. This means underglazes are super versatile and can potentially save you time if you are running a tight firing schedule. Using underglaze on bisque-fired clay has 5 advantages. The vessel is less fragile.
What happens if you put glaze over underglaze?
Another advantage is that you won’t risk messing up your design when you apply the clear glaze. However, you can apply the clear glaze right over the top of the underglaze without a firing between. This is best done if you applied your underglaze to bisque, because greenware can absorb glaze and crack.

Can you glaze unfired pottery?
Single fire glazing is where you glaze greenware (unfired pottery) and put it through the kiln only once. Potters have single-fired their work for years and a huge quantity of ceramic items through history was produced this way.
