Explanation:
Until the 1800s, people mainly used asbestos to make fireproof cloth in small amounts. Then during the Industrial Revolution, great demand arose for a material that could insulate steam engines. At the same time, the technology was developed to easily mine asbestos and combine it with other materials.
Asbestos boiler insulation was developed in the 1820s. Later, just before the Civil War, the first patent for asbestos roofing shingles was awarded to Henry Ward Johns. His company would go on to become Johns-Manville, the original titan of the asbestos industry.
