Hi Tom. Thanks for that article. There were a few interesting ideas but it fit very much in with those meandering "publish or perish" things that float around universities and make most of them suspect. The examples cited are all over the place...an Oldenburg sculpture, an original Russell wax, a Wyeth egg tempera, a Judd woodcut printed *in impasto*. For god's sake! Why didn't they bring in the Willendorff Venus to round it out as the most unrelated collection on earth. That they uncovered a "can" of Oldenburg's paint should be something of a clue as to what sort of alkyd it is .. like try industrial, with a lead molybdate pigment. Had they done their research they would have known that's auto body primer.

The beeswax they implicate they later turn around to state is tainted. Flying the face of their assumptions are the Fayum portraits which were either done in 100% beeswax or oil paints with a high percentage of wax. They are universally acknowledged to be among the most permanent of all paintings ever made. No one has ever shown alkali-bleached beeswax to be implicated in the darkening of the paint film.

I find it interesting that, although they mention palmitic and linoleic acids they do not mention other fatty acids which have been implicated in darkening and loss of flexibility in the paint film. We did extensive research into drying oils before we settled on offering only Stand Oil and Special Aged oil precisely because of their altered molecular structure which forms more stable paint films.

I found that article to be based in shoddy research and. most interesting because it did the usual "publish or perish" tap-dance about arriving at any conclusions. How could they arrive at conclusions with such far-reaching examples. It appears that the researchers were writing just another file designed to justify already received grant money and insure future grants. The results lead nowhere.

As to the technical grades of aluminum salts and soaps, New England Resins & Pigment is a pretty good source for large quantities.
