Rockland Pyrofoto for Ceramics is an amazing process whereby you can transfer (print) drawings onto ceramics. In addition, you can kiln-fire them. All you have to do is brush on the color, let it dry and then expose through an inkjet or laser transparency. The only equipment you need is either a halogen bulb or pure sunlight.
Various hues can be created by mixing colors together
Pyro can be used with various other color stains you may own
