Abstract

209,106. Maier, J. Dec. 29, 1922, [Convention date,]. Annealing.-An insulating coating for protecting parts of articles subjected to heat treatment, e.g. portions of tools which are being hardened, comprises a mixture containing hygroscopic substances in which water of crystallization is also present. A suitable coating may be obtained by replacing the water in the usual paste composed of water-glass, water and a refractory substance such as pipe-clay by a watery solution of calcium and magnesium chlorides in the respective proportions of 8: 10, the percentage of water added varying with the material under treatment.
