I did not get any printed material. It was all verbal. The quarry I was at was the Graymont in Genoa, Ohio. They have a web site and an 800 number. The GM is Mike Tate and the chemist is Ed. I think much of the info they have is from Canada and I believe the Canadian Goverment who studied various limes for historic renovations. Two were approved with theirs being one of the two. They have 45 gallon drums of putty dated June of 99 for $375 plus shipping (US). 3 gallon pails for $55 (US), plus shipping. I have since heard from Nicola Vigini. He uses a pre mixed putty from the same area for his fresco work and says he has never had any problem.

Dissertaion may be a strong descrptor, but when it comes to lime, there are so many processes and techniques of prep and use, some standard, others regional, that I find it sometimes baffeling. I have Millar's book written in the 1890's which has about 150 different ways to prepare and use plasters and this predates modern industrial processes and chemistry of double and triple hydrated limes. Even USG lists on their packaging that different product lines of theirs are not compatable when in fact they work fine together. Myself and others assume that they make these claims because it is easier for them to offer known "product lines" with no reasonable payback on studying compatability.

You obviously have a better grasp and understanding of lime prep and processes. Think you could give Graymont a call and post your impressions??? Thanks, Don C.
