ASBESTOS REFERENCES:

This book has a few references to when asbestos should, and should not, be used.  Here are the specific details:

About when NOT to use it:
In the section on H-W Fine Ground Fire Clays, it says:
"The addition of Portland cement, lime, asbestos, salt or other foreign materials to finely ground fire clay, to be used as mortar material for brick entering into high temperature operation, is not recommended.  Such materials, even in small proportions, may have a marked effect in decreasing the refractoriness of the mortar."

Section on Filler Materials for Joints says that asbestos CAN be used for outside joints. Here's the exact wording:
"The other class of filler materials includes inorganic materials, such as asbestos filler, asbestos rope, rock wool, or diatomaceous earth powder.  These materials are of relatively low refractoriness, and should therefore be used only in outside joints."

Section on "The Mineral Composition of Magnesia Refractories" mentions serpentine.  According to the glossary of this book, serpentine is "A group of hydrous magnesium silicate minerals. Chrysotile and antigorite .... are the most common."   This book's glossary also has a definition for Asbestos which mentions chrysotile as the more common form of commercial asbestos.

The quote from the section on Magnesia Refractories is:
"The mineral magnesite contains small amounts of accessory minerals, such as dolomite, serpentine, talc, chalcedony and quartz."
