You will hate it. It’s corse and rough and gets everywhere

“I hate sand. It’s coarse, it’s rough, and it’s irritating.”
-Anakin Skywalker

You can get it during a sandstorm on scorched

A whip is actually a very good way to get sand as you can run around using it and picking up sand of the floor however you will also pick up a lot of stone which can get heavy really quickly.

(I don’t know about other maps but this works well on scorched, hope it helps you get sand so you can make clay or something)
