A natural volcanic glass that expands up to 20 times its volume when heated quickly, as the water in it turns to steam, leaving a light, porous grain.
Watched ingredients get highlighted on every product panel you open.
- Where it comes from
- Mined, then heated to expand it.
- Why it's in the product
- A light carrier for the baking soda and scent in a litter deodorizer.
