Colour has been used in ceramics for a long time, but they are still being studied because there are only 50 ceramic colours. Copper, nickel, cobalt, manganese, chromium, vanadium and iron ions provide colours to ceramics. The colours are produced from the oxides of these metals. Ferrochromium fly ash, usually considered as waste, can be used to produce a range of glaze colours.
