Earthstone International is a US based manufacturer of foamed glass products. We 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.
Over the years, Earthstone has evolved into a professionally managed company that has developed, manufactured and supplied its customers with products that can be used for barbecue grill, kitchen, and bathroom cleaning as well as sanding. Earthstone sells to both the residential and commercial markets. We have a strong commitment to the natural environment and design all products to meet strict environmental and safety requirements. This commitment has earned us the Green America seal of approval and Green Clean Institute certification. In addition, we make all of our products in the USA at our plant in Santa Fe, New Mexico.
How our products are made:
Recycled glass is taken from landfills.
Did you know that most municipalities in the United States don’t truly recycle glass? The process to melt glass and form it into reusable material can be incredibly costly, so the glass that is turned in for recycling is mainly used in public art and for other similar projects. The rest is usually crushed and added into landfills anyway. Earthstone buys this crushed recycled glass to save it from being added to landfills.
Glass flour is made & mixed.
Earthstone grinds the recycled glass into a fine powder that feels like baking flour. Next, we mix it with a proprietary foaming agent that helps the glass flour rise like bread when it is baked.
Foamed glass is baked, cooled, & cut.
The glass flour is baked in our specialized kiln in Santa Fe, New Mexico at temperatures as high as 1600 °F. The baking and cooling process takes two full days, and then we cut and wrap the individual stones listed for sale on our site. Industrial products are made in a similar fashion.
