i mean i have the volcano and i would never put hash in the volcano on its own. they have the stainless steel sponge things that you can put hash on so it absorbs when it melts, but logic just says that the hash would melt through. infact i think i had to burn out some hash the guy i got mine from had melted down inside, but i just left it on high a few times overnight and it worked much better.

I would just never trust putting hash straight into the volcano with the basic bowl attachment. Though it seems like most people here add it to their greenery in the bowl which would work.
