I had posted earlier that I was going to try and make amber varnish using the amber colophony from Kremer. Their German homepage describes this as old material from a Russian amber-varnish manufacturer. Some here on the forum were skeptical about the nature of this resin and I wanted to follow-up and share my experience. To make a long story short: It didn’t work the way I had hoped. I tried to dissolve the colophony directly in boiled linseed oil. Nevertheless, I found that even temperatures around 250 deg C were not sufficient. Only a small amount appeared to dissolve in the oil (based on the color and smell of the resulting oil) but the vast majority formed a gooey black mass that was caught in the strainer. I am attaching some pictures to illustrate. Since at least for me this material didn’t work the way I had hoped I am starting with raw amber instead and will try to fuse/melt it myself.

Hello, please, help. I bought amber powder to make solvent free varnish (amber & walnut oil). I am an artist and wanted to try varnish as a medium. Anyway, I cooked amber in walnut oil, and nothing happened. As I discovered after amber has a high melting point. I also found here some instructions how to do it right way - first amber is melted, then after some cooling oil is added. Question about melting - what heat did you use? gas or electric stove? And about cooling - wouldn't amber crystallize when it's off the heat? e.g. damar resin crystallized immediately when off the heat I would also like to ask you about copal resin. I bought copal resin after my failure with amber. I cooked it with walnut oil in a deep frier and copal dissolved within 4 min. And because I have damar resin at home, I found that copal looks very much like damar. Copal I bought and damar have the same melting point ( tried to melt them together) both crystallize after and both crystalls dissolve in turpentine immediately. I thought that copal varnish is hard to dissolve in turpentine and , although, I didn't try to dissolve my copal varnish ( the sample of it is not dry yet) I thought crystallized copal should behave as dried varnish. Any thoughts, please? very informative forum. thank you so much, Elena
