We manufacture cast basalt that's used in applications that have a lot of wear and tear. This is pretty cool to see another application of basalt!

Rocks (of any type" and "wear and tear" don't really go together in my mind. Is this something on the order of jewel bushings in low speed mechanical clockwork?

I can't think of a lot of applications where I'd want any sort of rock as my bearing material but maybe I'm thinking too big.

Not bearings, this is "wear and tear" as in abrasion resistance. Cast basalt is used to create abrasion resistant pipes and flooring.

In the original article, "wear and tear" refers to chemical/corrosion resistance.

Considering the reactivity of most textiles compared to something like glass, I would imagine this has tons of utility anywhere you might need a textile in a chemical application.
