I am looking for a spirit varnish recipe that does not contain shellac. I am a guitar maker. I usually French polish with a shellac based varnish that also contains other resins. For this instrument, however, I can’t use shellac due to the believes of my client (please don’t make this the focus of the conversation). I tried modifying a sandarac based recipe, but the varnish was easily scraped off. I also tried sandarac turpentine and elemi (in alcohol), with the same results.
Sandarac varnish? I know sandarac is soluble in alcohol and insoluble in the oil. I do sandarac varnish Trying to pyrogeneticky. Linseed oil 300 to 315 ° C. Sandarac linseed oil is first dissolved and then immediately makes a precipitate. 20% is dissolved and 80% collides On the Internet I read several times that it is done sandarac varnish and I can not. Do not know how to cook sandarac varnish, without clots? What about the other oil? Thung, walnut oil?
