Is this oil based?I have been using a mixture of Bullseye shellac and isopropyl alcohol. I can't remember the exact mixture but you can try 50-50 as a start. I get excellent transfers as you can see. The bottle in this picture was mixed almost 5 years ago and it's almost empty. I used it up one Q-tip at a time. I don't post much but I do a lot of engraving. It's almost all production engraving on high dollar flutes. You can see the results on a 22 carat gold Head joint. I will admit that I use the Epson transfer sheets. I bought a huge stock of them back when they were available. There are other films that still work well. I believe Tom White sells some. And this solution is not toxic like some of the other solutions I have heard about.
One summer we had a class... everyone ate lunch outside under the grape arbor.
A gal knocked over a glass of apple juice. There were practice plates on the table.
There were no napkins that day, so I jokingly told her to let it dry and we'd see if it would take a transfer later...
So, the answer to your question is that yes, there are probably a lot of other substances that will work.
Some will attract ants...
Do you have a "Michaels" store where you live? They'd have damar.
I have also tried zapon lacquer with same result as dammar varnich. about 50% lacquer and 50% denatured alcohol. Think any shellack solution probably will give okey results.... The zapon lacquer solution is what I use today. Cant find any dammar varnish in the local stores where I livehas anyone found or tried an alternative to damar varnish? if so will you share? having a bear of a time finding some locally!
