Bags of asbestos! [Was: Use of asbestos in jewellery making]

180 different types of asbestos? I never heard of that, but it
makes sense! Back in the 70’s while a student at Philadelphia
College of art, I remember having brown paper lunch bags, full of
asbestos in powered/flake form, for use in soldering/stone
coverage!!! What a nightmare
