The colour imparted by Co(II) compounds to glass is deep blue.
Cobalt is primarily used as the metal, in the preparation of magnetic, wear-resistant and high-strength alloys. Its compounds cobalt silicate and cobalt(II) aluminate give a distinctive deep blue color to glass, ceramics, inks, paints and varnishes.
