A roofing shingle composed of asbestos fibers mixed with portland cement then molded under high pressure. In the mid-20th century, asbestos shingles were used as fireproof roofing and siding material. The natural color was gray, but pigments were used to produce black and green shingles. They were often prepared with colors and patterns that simulated slate (called asbestos slate).
