1 It is produced by precipitation through filtering, heating and quenching works.
2 Lithopone has mostly been replaced by titanium dioxide which is more durable,
3 but it is much cheaper.
4 It is used as a base for lake pigment and used as a inert pigment for paint,
5 ink and cosmetics as well as in a large range of applications in plastic industry.
6 It is used as a filler in paper, leather, and linoleum.
