E. C. Shuman of Owens-Illinois, Hydrous Calcium Silicate Heat Insulation (1952)

An article from the April 1952 issue of The Petroleum Engineer by E. C. Shuman, director of research of the Kaylo Division of the Owens-Illinois Glass Company, with the issue's contents page. It describes hydrous calcium silicate pipe and block insulation, sold as Kaylo: a mixture of lime and silica "containing small amounts of asbestos fiber for binding action," developed by Owens-Illinois from 1938. Shuman praised its light weight, strength and savings, and wrote that applicators liked the fact that it "is non-toxic and 'easy on the hands.'"

What it shows

This is a trade-press account of Kaylo by the man in charge of its research, written for refinery and pipeline engineers. It mentions the asbestos in the product only as a binder and says nothing about dust from sawing or cutting it, although it describes workers cutting the insulation "with an ordinary saw, or even with a knife" to fit pipes.
