Uses:
1.Lithopone is a white pigment composed of a mixture of barium sulfate (****0%) and
zinc sulfide (****0%) with trace amounts of zinc oxide.
2.It is produced by precipitation through filtering,heating and quenching works.
3.Lithopone has mostly been replaced by titanium dioxide which is more durable
