xraymymind Report post Posted October 9, 2020 Hey all, I wonder whether anyone here has made a Resin/Linseed Oil varnish, to which they did not add any Turpentine (or other solvents) while it cooled (which is something I have always done). What was the outcome like? Were you still able to thin it with a solvent to brush later, or keep it thick for glazing purposes etc.? Any opinions on this would be much appreciated.

If you are talking about making a solvent free oil varnish than yes many here have done that. Typically 1:1 ratio of linseed oil to cooked resin by weight. Have a look at the Bass Book by Roger Hargrave. It is all there. Quote Share this post Link to post Share on other sites
JacksonMaberry Report post Posted October 9, 2020 @Jim BressBress makes a fine solvent free varnish. Perhaps he'll share his thoughts. I have an article coming out soon and once it is printed will share the technique on MN as well. I prefer a 3:2 oil:resin ratio myself for a variety of reasons and especially absent solvents a fatter varnish should brush easier. Quote Share this post Link to post Share on other sites
