MAC (McCrone Accessories & Components): Reference Manual w slides (1989)

The manual for McCrone Accessories & Components' Asbestos Reference Set, copyright 1989, a 25-slide kit meant as an aid in identifying asbestos and other fibers and particles found in insulation samples. Data sheets give refractive indices and dispersion staining colors for chrysotile, amosite, anthophyllite, crocidolite, fibrous tremolite and other materials such as fiberglass, wollastonite and talc, and separate sheets describe four actual insulation samples. A list of training photomicrographs follows. It says amosite is often used in high-temperature boiler insulation and vermiculite with chrysotile as ceiling and beam fireproofing.
