Thanks Ron,
Perhaps I would be better understood if you looked at an article I read recently over the net, dealing with conservation issues in paintings, sculpture and works on paper.... You can view this article at:
http://palimpsest.stanford.edu/waac/wn/wn20/wn20-1/wn20-108.html

It is the ratio of fatty acids that vary. forgive me, i meant to say "technical grade" aluminum stearate, 99%, not "pharmeceutical" as there appears to be a great variety in grades which would account for different fatty acid ratios. Please read the article and tell what you think. I found the information regarding carbon black and cobalt blue particularly interesting.

Where do you obtain your aluminum stearate and is it 99% technical or what percent,(it should be indicated). thank you. tom
p.s. also I read your article on fossel copal on your web site which i enjoyed and was glad to find. It is my understanding that congo copal has a lumpy, alligator-like surface, very characteristic of its origin. Have you heard this? Ultimately I believe the test is in alcohol. True fossel copal will not solve in alcohol like soft copal.... fossel copal changes into a plastic-like substance, but doesn't solve. This has been my experience.
