18,090. Ferrell, J. L. Aug. 21. Fireproof coverings and compositions.-Mixtures are made of solutions of sodium silicate, chloride, and hydrate in about the following proportions :- 4 parts of sodium silicate of 40‹-53‹ BÚ., one part of sodium chloride of 24‹ BÚ., and one part of sodium hydrate of 26‹ BÚ. The resulting solution is reduced to about 20‹ BÚ. by the addition of water, and, when a denser solution is required, more sodium silicate is added to this latter solution. The compounds are used for fireproofing wood and similar cellular materials.
