Re: Clay Slips and colorants...

Larry, You can make your own colored slips with white clay slip from the
potters wheel, or just slake down some totally bone dry chips of clay
with water. Try adding some Mason stain or oxides like cobalt (a little
goes a LONG way), Copper, Manganese, Iron, Rutile, etc. Unfortunately,
I have not made any of these for so long, I can't give you a recipe, but
surely you can find some in a book or someone else in here will know
what to tell you. The problem with using just any old slip is that if
they don't match the shrinkage rate or the Maturing temperature for
firing of the clay you happen to be using, they might flake off. If you
want to make black or a darker brown slip, you can use brown clay or red
clay and use something to darken it more, but you will want to use white
if you want a color like blue or green, etc.
