Slate and Soapstone
Versatile, Chemically Resistant Materials
A traditional use of both these materials was the laboratory table top in chemistry labs. That application alone should serve as a great testimonial to the chemical resistance of the materials.
Being of the softer varieties of dimension stone types, neither of these materials is known for particularly high abrasion or scratch resistance, yet they are both used a flooring and countertop products.
Soapstone is highly heat resistant, and has been used in fireplace surrounds frequently to take advantage of this property.
Slate, being of laminar construction, has the ability to be processed into thin sheets and still maintain serviceable strength and rigidity. This property makes slate the only dimension stone having been used for blackboards and roofing shingles. It was also traditionally used as the cloth-covered playing surface of billiards tables.
