Barium Chromate is a yellow-colored, sand-like powder. It is used in artists' colors, in coloring glass and ceramics, as a corrosion inhibitor, and in safety matches.
Barium, as a metal or when alloyed with aluminium, is used to remove unwanted gases (gettering) from vacuum tubes, such as TV picture tubes.

Procedure
The barium mineral, benitoite (barium titanium silicate), occurs as a very rare blue fluorescent gemstone, and is the official state gem of California.
Note
Barium is a soft, silvery-white metal, with a slight golden shade when ultrapure.[5]: 2 The silvery-white color of barium metal rapidly vanishes upon oxidation in air yielding a dark gray layer containing the oxide.
