Description: The embodiments of the invention in which an exclusive property or privilege is claimed are defined as follows.

1. A composition for use in forming a heat and flame resistant paint which comprises from about 14 to 19-1/2 parts by weight of finely divided clay, from about 1-1/2 to 2-1/2 parts by weight of finely divided asbestos, from about 14 to 19-1/2 parts by weight of finely silica sand or silica flour, from about 18 to 30 parts by weight of soluble glass, from about 5 to 9 parts by weight of red or black iron oxide or white titanium oxide, from about 1/2 to 1-2/3 parts by weight of rosin, and at least about 3-1/2 parts by weight of an aqueous solution containing 500/0 by weight sodium hydroxide.

2. A composition as claimed in claim 1 in which the aqueous sodium hydroxide is present in an amount from 3-1/2 to 5 parts by weight.

3. A composition as claimed in claim 1 comprising about 16 parts by weight finely divided clay, about 16 parts by weight silica flour, about 6 parts by weight red iron oxide, about 1 part by weight rosin, about 2 parts by weight asbestos, about 20 parts by weight soluble glass and about 4 parts by weight of an aqueous solution containing 500/0 by weight sodium hydroxide.

4. A composition as claimed in claim 1 in which the pigment is red iron oxide.

5. A composition as claimed in claim 1 in which the pigment is white titanium dioxide.

6. A composition as claimed in claim 1, 2 or 3 in which the finely divided material has a particle size of not more than 200 mesh.
