Can you color slip with glaze?

The slips are made from porcelain clay, so it can safely go on the bottom of the object if you want color to go all the way around the form. Since the slips are clay, glaze can be applied over the slip (after it has been bisque fired). Another popular way to use the slips is a through technique called “sgraffito”.

Because the slip shrinks it will tend to flake or peel of bone dry clay. Regular slip is, therefore, best applied to soft or leather hard clay. However, you can also use a slip trailer to apply engobe. In this case, it is possible to slip trail onto bone dry clay and bisque ware too.

A glaze is a paint composed by a bunch of chemicals that, when added to a bisqued piece, it will make that glass shiny cover. An underglaze is a paint composed by a bunch of chemicals that you can add to greenware or bisqued pieces to add color but it will not add the glass part.

What is the point of underglaze?

Underglazes are used in pottery to create designs and patterns that come up through the glaze covering them. This can give the surface more visual depth and character. Although they are often used under clear glazes, they can also be used under other, generally light-colored, transparent glazes.

Why is slip used in pottery?

Slip painting matches the clay's shrinkage better than adding other thicker paint or glaze after firing. It is also applied before the bisque firing and is bisqued along with the object. Then you can use further underglazes and engobes to define decorations and images before the final firing.
