Firing Range: 999-1305c (Cone 06-10)
Full-bodied non-toxic underglazes. Fully intermixable.
When applied correctly to greenware or bisqueware they provide full opaque streak free coverage: On greenware, the clay is fired to bisque temperatures then covered with a suitable clear glaze and refired to seal the ceramic piece.
On bisqueware, the Underglaze decoration should be thoroughly dry before being glazed over and then fired to recommended gloss temperatures to seal the ceramic piece.
Most of the underglazes may be left unglazed to create a matt look similar to engobes. If fired higher on an appropriate clay body, the result may be slightly satin in appearance. If used in this way, they are mainly suitable for use on non-functional ware. To obtain optimum results, 2 – 3 coats of Underglaze should be applied using a well-loaded brush. Ensure each coat is dry before applying subsequent coats at right angles to one another (i.e. crosshatching).
Underglaze colours are designed for use directly from the bottle, although they may be sprayed or sponged. Clean water may be added to achieve alternate finishes or to adjust consistency for spraying.
