#5, RE: Making your own pigments Posted by admin on 12-Jun-05 at 01:43 PM In response to message #4 crush/grind it down to fine powder, then grind into the paste with water. after that mix some of the paste with putty lime and observe for 24 hours. If the color will change then it is not good. If the color stays as it was when you just mixed your paste with lime then it is good.
