stone-like slips

These recipes are from Zakin's book on Electric Kiln Ceramics.

Some of the clays used in the recipe are coarse and the slip should not be
strined. The result will be a coarse, sandy-textured surface, not for
functional pieces. They may be applied by dipping, spraying or brushing.
They may be applied to greenware or bisqued ware. They may be used alone or
with stains and glazes. The appearance when fired is soft and sandy.

I've applied them to bone dry sculptural work, bisqued them and then have
rubbed stains or oxides into the recesses, sponging off, then fired again
for permanence. They are quite versatile.
