UG600 - Black Underglaze

UG600 - Black Underglaze

For Cone 06 - 10

A deep and intense black.

Underglaze is designed to add color to pottery without chemically interacting with other glazes. This allows you to add color without worrying that you’ll change the color or consistency of your glazes. A mixture of colorants and a little bit of clay, it can be applied to greenware (unfired clay) or bisqueware (fired to cone 08 to 06 to prepare for glazing) and ultimately fired to any cone. It does not create a glass, so does not make clay food-safe on its own. 

To apply: Always mix first before each use! Then brush three coats on greenware or bisque ware, alternating direction with each coat for a smooth, even application. Let dry fully between each coat. If applying glaze over the top, we recommend applying the underglaze to greenware and then firing to bisque before applying the glaze. Apply any desired glaze over the top, but remember that opaque glazes will mask the color of the underglaze.

If the consistency seems thick, first mix thoroughly. If it still seems thick, add water SPARINGLY to thin it down. If too thin, leave the container open to let some of the moisture evaporate.

Note that mixing glazes together or applying one on top of the other may cause the glazes to react differently than you expect. We recommend that you always test a new glaze combination and clay/glaze combination to see how it performs.
