NUPICK 10 Pound Fire Glass, 1/2 Inch Reflective Fire Glass, Fit with Fire Pit Glass and Fireplace Glass, Black

Can I use these in my table top propane fire pit? It came with the lava rock and they said not to cover the holes where the fire comes out of? Help.

Can you use with wood burning pit?

Can the glass replace lava rocks

Can you use these with regular candles?
