It’s a long story as to why, but I stumbled across some online and historic pictures of asbestos-mining and processing. The collection is presented by the McCord Museum of Montreal, which looks to be quite an interesting place. Its online presentations include a great collection of photographs and text showing asbestos mining in Canada starting in the late 1800s and moving up through the 193os or so. The photos of the steps in processing the ore are especially interesting as they show clouds of fibers, and lots of work being done by women and children. The website has several very nice tools to view the photos as a film or individually, including a zoom feature. The presentation is well worth viewing simply as a history lesson even if you are not involved in asbestos litigation.
