These are just extracts, the article has more notes and references. Asbestos is a group of naturally-occurring silicate minerals that are made up of fine, fibrous crystals. Three of these are crocidolite (blue asbestos), amosite (brown or grey asbestos) and chrysotile (white asbestos).Asbestos becomes a hazard when microscopic fibre fragments become airborne and are inhaled.ut by one of the most unfortunate sleights of hand in scientific history, this demonisation was extended to include white or chrysotile asbestos, magnesium silicate, just because it shares the same name. a product that poses no risk to human health and is chemically identical to talcum powder.
