Stain is a word in ceramics that has a completely different meaning from that used outside the ceramic language.

Stain as used in ceramics: stains are inorganic colors purchased as powder that are added to different types of bodies, slips, glazes and enamels and used for in-glaze and under-glaze decorating, Stains are prepared to use at different temperatures, but the same colors when fired at different temperatures are never exactly the same.

Stain usually describes foreign matter that has penetrated into a material chemically and damaged it. It can be another color or damage to the original color resulting in a stain that is not easy to remove.
