Crash..this is a dab rig. The bowl is crystal, and using a small butane
torch you heat the bottom of the bowl til it's pretty much glowing, then,
you would get a small amount of oil on the end of a "dab stick" (basically a short steel rod), and then you'd "dab" that oil on the inside of the very hot bowl. The oil doesn't burn, it vaporizes while you are inhaling the vapors. Decent quality concentration (oil) will run about $40 gr.

JMHO, but not recommended for new users.
