- logfromblammo 11y agoTechnically speaking, I think pumice is a type of glass, and silicates are actually inorganic polymers (...-Si-O-Si-O-Si-O-...). The problem is that microbeads are new to the ecosystem, and no species larger than a bacterium has yet adapted to suddenly having a lot of anthropogenic plastic particulates around.
