About Earthstone International

About company

Earthstone International is a US-based manufacturer of foamed glass products. They recover glass from US landfill sites and recycle it to create environmentally responsible cleaning and sanding products that work. Earthstone was founded in 1995 by Gay Dillingham and Andrew Ungerleider to create an eco-friendly alternative to pumice without having to use the conventional process of strip-mining in the mountains in New Mexico and elsewhere.
