here is the info you are looking for, this information is how people do it commercially
The same components used to make ceramics and glassware is used in making the colors themselves, These compounds are then mixed with compounds known to man for thousands of years, like the color blue is made with Cobalt, Green is made from Chromium Oxide. Over time new colors have been added, like the color red has only been around for 50 or so years. The combination of the compounds and a Frit are then mixed with oil so they can be applied to a product. Unlike colors used in paintings almost all ceramic colors can??t be mixed because they are made with unstable compounds.
After the items are printed onto the ceramics or glass, they are then Fired, Firing is when a product is baked at high temperatures, the color and the glaze fuse together and the imprint of the ceramics and glass becomes permanent when the product reaches 1400F for Ceramics and 1100F for Glass. Most modern ceramics are fired 3 times before people even use them, the first is the biscuit firing which is at 2200F, then it is glazed which gives the ceramic it??s color and fired at 2000F, after that the colors are applied at the product is fired for the last time at 1400F to make sure the colors become permanent.
