What is the difference between underglaze and overglaze?
What is the important difference between overglaze and underglaze is when the paint is apllied. In the case of overglaze, you burn the glazing on the porcelain and then paint it. While when using underglaze the paint is applied on the unglazed porcelain and then the glaze is applied over the paint.
What materials are found in an overglaze?
To make an overglaze you need three ingredients: a frit, a colorant, and a medium. The frit is the glass base. An important distinction for overglaze frits is they are milled very fine like talcum powder so they will not seem gritty when used as a paint. Both finely ground white and clear are available.
What is the difference between glaze and enamel?
When the substrate is a ceramic, the coating is called a glaze. When the substrate is a metal, the coating is called a porcelain enamel. When the substrate is a glass, the coating is called a glass enamel.
What is Overglaze used for?
Overglaze decoration, overglaze enamelling or on-glaze decoration is a method of decorating pottery, most often porcelain, where the coloured decoration is applied on top of the already fired and glazed surface, and then fixed in a second firing at a relatively low temperature, often in a muffle kiln.
What is an advantage of using underglaze instead of regular Overglaze?
Because underglaze has a much lower glass content than glaze, it can be used for much more detailed decoration. Fine details can be painted onto greenware or bisque ware and it will not run or bleed as much as a colored glaze. Underglaze can lose its pigment if it is fired in the kiln at too high a temperature.
What does Overglaze mean in ceramics?
What is the purpose of Overglaze?
How long does a luster firing take?
However, I can be impatient, so now I tend to add pieces to my kiln as I apply the gold to them, shut the lid when I’m finished, and crank it up to high. It only takes 2–3 hours for my kiln to get up to temperature, and another 4 hours to cool.
What is glaze enamel?

When do you apply decoration to a glaze surface?
A method of applying decoration over the glaze surface of ceramics. It can be done before or after the glaze firing. ‘Onglaze’ decoration can refer to two very different processes. The first involves the application of liquids applied onto the fired glaze surface. These include china paints, lusters, gold, and other metallics.
What makes up the frit of an enamel?
The enamel consists of a transparent glass like substance, a frit, which is a mixture of silica and fluxes that are fused in a second lower temperature firing that combines the metallic oxides of iron, cobalt, manganese and lead.
