Italian lacquer

Under the Italian varnish implies, as if known, a transparent oil varnish covering the stringed instruments of Amati, Guarneri, Stradivari and other Italian masters. The recipe for this varnish was lost around 1770. Since then, the violins are also common, all stringed instruments are covered with alcohol varnishes, and very rarely with dark brown oil paints. Because of this, we consider it beneficial to bring a recipe for Italian varnish created by the famous Russian violin maker A. Lehmann.

Before you act the ground, you need to take care of the color of the log. A well-sanded wood is covered with an aqueous solution of brown sepia paint (liquid extracted from cuttlefish). At what time the paint, applied with a very moderately wide brush, dries, the log is polished with a very small flint paper and also covered with a layer of colorless, hastily drying oil varnish. Then the log is again polished with the same fine flint paper, but this time with wooden oil, after which it is wiped dry with a clean rag also covered with a round soft brush with colored varnish, which dries very quickly, so after a day it is already good for polishing with flint paper with oil or water. Color lacquer is composed of colorless (it is best to take amber in oil with a strong drying), which is mixed with well-erased paints in the tubes: brown, red and yellow.

To cover the violin, 2 tablespoons of lacquer are enough, but no more than 2 coffee beans can be painted. You can use the following colors: Indian also Japanese yellow, varnish of Robert No 7, brown varnish, asphalt and also krap varnish. It is best to color varnish on a silver platter. First, paint is released from the tube, carefully rubbed with a glass pestle, the varnish is added to the lacquer and the lacquer is also mixed thoroughly with the paint. Then, taking a round brush, slowly apply varnish on the tree. The varnish dries immediately, but therefore it should not be done with a brush on one room more than 2-3 times. It is necessary to take care to act the ground with the help of glue and alcohol varnish, which too deeply enters the log also greatly affects the sharpness of the instrument sound. The fast-drying oil varnish, against, almost never enters the log, also forms a soil that does not crack, and does not peel at all, as if it were alcohol. After varnishing the brush, it should immediately be rinsed in kerosene, but then rinsed with soapy water.

It remains to be noted that the coating of a significant number of new plus old stringed instruments with Italian varnish Lehmann gave very good results.

Alcohol varnish for violins

Take 1 lobe of mastic, 5 elements of alcohol, 2 parts of turpentine, 2 elements of linseed oil, mix, allow to stand for a week with frequent agitation and also drain a clear liquid (The Brit and Gol. Drugg).
