Ceramic stains / colorants applied to a greenware or bisque surface and usually covered with a clear glaze.
Underglazes can be translucent or opaque, with opaques used for large solid area coverage and translucents used for details and decorations.
An oversimplification is: Opaque underglazes are mostly clay with pigment; translucent underglazes are mostly pigments with little clay. Applying opaque underglazes to greenware can help keep them from separating from the clay body during the firing.
Generally, both types can be intermixed, in each category or between the two, producing a palette containing hundreds of color choices.
Underglazes may be used directly from the jar, but should be put into a separate container to avoid possible contamination of the remaining product in the jar. Apply the first coat with even consistent brush strokes. When the dark wet look has disappeared, apply the second coat at a right angle to the first. Again, when the wet surface has disappeared the third coat is applied at a right angle to the second coat. This will assure better coverage and help to avoid streaks and thin spots.
Lightly dampening the surface with a moistened sponge just before painting allows for a better adhesion to the ware surface.
NOTE TO TABLEWARE PRODUCERS All finished dinnerware products must be tested and approved as food safe by a certified laboratory due to possible variations in firing temperatures and possible contamination.
