Question:
What is underglaze?
using underglazes
When using underglazes, do not backstroke when applying, as this will cause a pile-up of paint or a pulling off of the paint already applied.
drying underglaze
Remember that your colours must be dry before taking any nest step, whether it is firing or adding design work over your underglaze base.
Underglaze design work
Underglazes are poor choices for design work. Since it is necessary to apply three coats for effective coverage, you can see how difficult it would be to make three tines directly on top of each other.
Proper overglaze decorating
Proper overglaze decorating begins with the greenware. Greenware which is to be overglazed should be carefully cleaned and fired to cone 04
underglaze application
You can apply one colour of underglaze over the other. Being opaque, the top colour will cover the underlying colour completely.
Underglaze application
Underglazes are designed for all over coverage such as for background work. They are not good for detail work
Underglaze use
Underglazes should be used only on greenware. They can be used on bisque however and fired before a glaze application
underglaze colours
The colour in the jar of underglaze is not the resulting colour when fired. You can change the colour of underglazes with the addition of one-strokes (pure colour pigments) in varying quantities. Since you still will not be able to tell the colour you have made until after the piece is fired, it is recommended to make a test-firing of piece to be sure the colour is what you want.
Firing
In firing an overglaze, the glaze is softened to the point where the overglaze settles onto the softened surface and becomes a part of that surface.
Choosing the right brush?
When using a brush to apply overglazes, it is best accomplished with the largest brush suitable to the object being decorated.
wipe off rims of paint jars
Always wipe off rims of paint jars before storing. Store jars upside down. This will make opening and mixing easier.
colours/shelf life
Some colours have shorter shelf lives than others. They may become like a gel if too old. You can salvage these by stirring or even running them through your blender. Add a drop of water at a time to get the proper consistency.
