Underglaze pencils, pens/brush, and crayons can be great for ceramic artists who may have started with a background in painting or drawing. When you are used to working with paint brushes, pastels, or pencils to create imagery, dipping a piece into a glaze bucket, or trying to paint with glazes that are immediately sucked up by the porous bisque surface can take some getting used to. And then there’s the fact that the unfired color of a glaze is often not what it looks like fired. That’s where underglazes come in. Underglazes are basically clay-based materials with ceramic stains and metallic oxides added and they come in a variety of forms – liquid, dry, chalks, pens and underglaze pencils.
