What happens if glaze is too thick?
Fluid melt glazes, or those having high surface tension at melt stage, can blister on firing if applied too thick. Glazes having sufficient clay to produce excessive shrinkage on drying will crack (and crawl during firing) if applied too thick. Fluid melt glazes will run off ware if applied too thick.
Do you have to glaze over underglaze?
Amaco GDC’s can be used as underglazes or glazes, so they have silica and should be applied to bisque. 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.
