I shall talk with her about this tomorrow. To make India ink, this fine black dust is mixed with a liquid. Cobalt is the only thing I can think of that might keep its color since cobalt is used to make blue glazes. India ink is used in tattooing because many tattoo artists don’t feel safe with anything else. However, this does not mean it is safe to use on one’s skin. But that depends on what is used for the pigment. Many people believe that yes, India ink is safe to use on tattoos, because it is used by tattoo artists for hundreds of years without any problems. Now colored ink would be a different story, and most likely, if used would change color, probably to black. One does not want to fire a piece that is not totally dry or the residual water could cause the piece to explode. Water in the ink is irrelevant since clay is only soft because of its water content. You will want to prop the tile up so it is in position to represent a mug or vase. Clear glaze one but not the other - so two bisque, one glaze one no glaze, this will show if it runs with glaze on top. Try on tiles that are bisque, as well as green. Maybe research what the Romans used for thier black? I believe it was slip, but maybe not. If its still made with soot or other carbon, then it is not goin to go anywhere, even in the kiln, soot is created by fire after all. I don't see why black India ink would not work. I would have carved into the greenware, fired the piece and then glazed it. A colored slip is what is used to decorate greenware. 239000000203 mixture Substances 0.Typically, greenware should not be glazed.Google has not performed a legal analysis and makes no representation as to the accuracy of the date listed.)
