SP71 - Cobalt Blue

CONE 06 - 1

A traditional cobalt blue.

Low-fire glazes, such as this, should be used on low-fire clay (meant to be fired to cone 06 - 04).

To apply: Always mix first before each use! Then brush or dip onto bisque-fired pottery (pottery that has been fired to cone 06 - 08). If brushing, apply three layers, alternating the direction of the brush strokes with each layer to create a smooth finish. Let dry completely between each coat (until it completely loses its sheen), but do not over-dry or the glaze may crawl. If dipping, dip and hold for three to five seconds, then remove from the glaze and shake off the excess. A second layer can be applied, but three or more layers will result in the glaze running off the pot. Let dry until it loses its sheen between each coat. Fire to cone 06-04.

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.
