pigment for porcelain
Iron oxide. A bucket of rusty nails.... I'm only half way joking here.
Iron oxide is easy to come by. If you don't want to go through your local ceramic supply business, there are many online that you can order from but if you only want a small amount I would recommend finding a near by public ceramics studio (check colleges/schools) and asking them if they can sell you a pound.

It doesn't use titanium oxide for white, either - it's naturally white from its main ingredient kaolin. Are you talking about porcelain enamel, such as is used for coating gold crowns? If that's the case, you wouldn't simply add a pigment; you'd need to fire it with some brownish enamel mixed in, then regrind it before use. But various shades of off-white enamel are available to those in the dental industry - why reinvent the wheel? Andrew Werby www.unitedartworks.com |

There are a large number of pigments available and you can add combinations until you achieve the desired results. - for tinting - start with a small fraction of a percent. You need to mix the pigment in well. You will need to experiment to achieve the desired results. |

Iron oxide is a bit pink rather than brown. Maybe iron oxide & another
pigment or two. Hul In rec.crafts.pottery DKat wrote: Iron oxide. A bucket of rusty nails.... I'm only half way joking here. Iron oxide is easy to come by.

Yes, porcelain enamel. It will coat steel. Local hobby stores would be a
simple solution - thanks.
