Hide and AIDS infected needle in the wipers.
Entire books have been written on this topic. Some colors (red) are much harder to make come out consistantly.
It will if you find the right paint for it. The chemical industry has produced a new number of paints that can be used in all those kind of materials, to use outdoors, etc. Check in a good art-craft shop, ask the salesperson for paints on ceramic. There is one place in my area named Michael's I don't know where you live, but they carry all kind of paint. Good luck!
A glaze is made up of silica, alumina, fluxes, opacifiers, and colorants. The colorants are of course what makes a glaze colorful. Colorants are generally metal oxides and cabonates. Depending how that colorant reacts with the rest of your glaze ingredients and heat /temp and firing atmosphere is what color your get. As an example copper carbonate generally gives you a green of some sort tho sometimes can give you pinks, reds or purples.
A thin layer of Vaseline should do the trick.
