What are the good and bad uses of clay?

Answer 1

I don't know exactly what you're asking.

Good uses of clay are in mud bricks and ceramics.

A bad use of clay is in your lawn or garden because it inhibits plant growth.

Answer 2

You'll need to be more specific than this? Clay what? Clay roof tiles? Metal clay? Clay for pottery? With or without a potter's wheel? With or without firing in a kiln?
