Re: Paper - baby oil Digi Negs
If I can kibbitz on the subject of turpentine and mineral spirits. (Only because I paint as well as photograph and I have a lot of experience with solvents.) Turpentine is refined from trees (basically) and should not be confused with mineral spirits which are refined from petroleum. I'd also like to caution that there are varieties of mineral spirits and the stuff that you buy at the hardware store in the gallon can isn't quite as pure as the stuff sold in art supply stores. To play it safe, I recommend that you consider the mineral spirits produced by the Gamblin company and sold as "Gamsol". This is the odorless variety and, as I mentioned before, just because it's odorless doesn't mean that you shouldn't take precautions like good ventilation, limited contact with skin and no open flame. Turps wouldn't be very good for this application because there will always be a residue of the resins left behind. I'm following this with interest and would be testing all of it out here as I have most of the materials on hand...but the whole place is an absolute mess since we're painting and everything is put away for safety. In oil painting we are cautioned about using the oils that dry very slowly or never dry at all. I'll try to find a list of those in my reference books but I know that linseed, safflower and walnut oil are prefered in painting because they DO dry. The drawback with the organic based oils, though, is that they'll eventually rot paper or fabric unless it's primed. If they have any of the petroleum based wax on hand, you might run a test with that...seems like the craft stores carry it for candle making and it's cheaper than beeswax...since it's a petroleum derivative, the rotting problem would probably not be an issue. I assume that the wax paper that we use in the kitchen is waxed with a petro based wax...is that transparent enough for your purposes? Maybe good ol' Vaseline is the way to go...I could only imagine that that would get rather sticky after a while. Argon/JG
