The technology of manufacturing varnishes for
Glossary of terms
Under the Italian varnish is meant, as if known, a transparent oil varnish covering the stringed instruments of Amati, Guarneri, Stradivarius and other Italian masters. The recipe for the composition of this varnish is lost around 1770. Since that time of the violin, all the string instruments are also covered with alcohol varnishes and very rarely with dark brown oil. As a consequence, we consider it beneficial to bring the recipe of Italian lacquer, created by the famous Russian violin maker A. Lehmann.
Before acting the soil, you need to take care of the coloring of the log. A well-ground wood is covered with an aqueous solution of brown sepia paint (liquid extracted from cuttlefish). At what time the paint, imposed by a very moderately wide brush, will dry out, the log is polished with very fine flint paper, and is also covered with a layer of colorless, hastily drying oil varnish. Then the log is again ground with the same fine flint paper, but this time with the wooden oil, after which it is wiped dry with a clean rag and also covered with a round soft brush with a colored varnish that dries very quickly, so that in a day it is ready to be ground with flint paper with oil or water. Colored varnish is made from colorless (best to take amber in oil with strong drying), which is mixed with well-worn colors in the tubes: brown, red and yellow.
To cover the violin, 2 tablespoons of lacquer is enough, but the paint does not have more than 2 coffee beans. you can consume the following colors: Indian, also Japanese yellow, Robert No 7 varnish, brown varnish, asphalt, as well as krap-varnish. It is best to make a colored lacquer on a silver platter. First, the tube is let out of the paint, thoroughly rubbed with a glass pestle, the lacquer is added and the paint is also thoroughly mixed with the paint. Then, taking a round brush, apply a lacquer slowly onto the tree. The varnish immediately dries up, but that's why you should not brush more than 2-3 times in one room. You must be careful to apply the primer with glue, also alcohol varnish, which is too deep in the log, also greatly affects the sharpness of the sound of the gun. Quickly drying oil varnish, against, almost does not enter the log, also forms a soil that does not crack in any way and does not peel, as if alcohol. After lacquering the brush, immediately rinse out in kerosene, but then rinse with soapy water.
It remains to be noted that the coating of the Italian varnish Leman a significant number of new plus old stringed instruments produced very good results.
Take 1 share of mastic, 5 elements of alcohol, 2 parts of turpentine, 2 elements of linseed oil, mix, allow to stand for a week with frequent shaking also drain the clear liquid (The Brit and Gol. Drugg).
