Asbestos, Its production and use With some account of the asbestos mines of Canada

A vivid portrait of one of nature’s most paradoxical minerals, this work explores the curious blend of strength and flexibility that makes asbestos so remarkable. Drawing on letters from Canada and a wealth of contemporary sources, the author guides listeners through the mineral’s geology, its striking presence at world exhibitions, and the ways it was woven into fabrics, fire‑proof clothing, and industrial products in the late nineteenth century.

The narrative then turns to the mining heartlands of Italy and Canada, offering detailed comparisons of the two main deposits and vivid sketches of the Thetford, Coleraine, Broughton and Wolfestown groups. Along the way, colorful anecdotes reveal how workers first discovered asbestos’s fire‑resistant properties—sometimes to the amazement, sometimes to the alarm—while the text outlines the expanding commercial applications that were reshaping manufacturing at the time. Listeners gain a clear sense of how this “indestructible” material entered everyday life, setting the stage for its later, more controversial history.
