To obtain fine lustrous and durable varnishes from solutions of rosinates it is advisable to use the solution rather thin, and to apply a second coat as soon as the first is dry. The resistance of these rosinate varnishes to atmospheric influences is very great, long exposure to the continuous action of air, sun, and rain leaving the lustre of the varnish unaltered. These varnishes also offer great resistance to the action of chemicals. Frequent washing of a varnished object with soap and water affects the lustre only very slightly and the coats resist solutions of carbonate of soda or potash even better than they do soap; but fairly concentrated solutions of caustic soda or potash attack the varnish rather strongly, decomposing the rosinates with separation of alumina or zinc oxide while the alkali combines with the rosin acid forming a soap soluble in water. It is safe to assert, however, that as regards resistance to atmospheric influences and the action of chemicals, the rosinate varnishes are quite equal to the best oil varnishes, at the same time they have the advantage of being very much cheaper. Resinate Paints. The solutions of rosinates in oil of turpentine prepared by one of the previously described processes can be mixed with various powdered pigments to produce bodies which can be used as paint after the addition of a suitable amount of turpentine. The paints are made by pouring over the perfectly dry fine powder of the pigment enough solution of rosinate to form a paste, thin enough to be worked up in an ordinary colour mill. The first passage through the mill usually renders the mass somewhat stifl. er so that a little more rosinate solution must be added to it. The ma. . . This item ships from La Vergne,TN.
