Iam sure that someone on Maestronet will have tried this so I searched and searched and searched again but couldn't find anything about it on this site. So I thought I would risk asking couple of questions! I recently looked at the old book, via the magic of the internet, " The Art of Painting in Oyl" by John Smith, 1705 and he describes making linseed oil dry quicker by adding "copperas" that has been calcined/burned on a fire shovel, I presume this is ferrous sulphate and the heating maybe drives off the water of crystallization and turns the green vitriol/copperas white. Here is what he writes The next page he describes "one inconvenience" of this is that it makes the oil a "deep reddish" colour! I read this and thought this deep reddish colour sounds like it would be nice on a violin. I seached on Maestronet and on the internet generally and could find nothing so please forgive me if I am asking dumb questions, Has anyone tried this and does it work well as a drier? Is there a risk of the iron in the oil turning dark over the years, like some of the very dark violins that originally were red? Any information and advice will be gratefully received, in the meantime I feel a strong urge to go off and polish my fire shovel!
