Does disintegrating perlite produce clay?

Question

Perlite sand is extremely fine. Is it clay? Will it cake up my soil over a long period of time(e.g.10 years)?

Answer 1

If you mean perlite, no, it's not clay and doesn't turn into clay, it is made from expanded volcanic glass, see here https://www.gardenersworld.com/how-to/grow-plants/what-is-perlite/
