Zinc is a poor choice in butane and essential oils.

Copper is a better one, if kept clean.

300 series stainless or borosilicate are best.

Graywolf Reviewed by Graywolf on . Did a small scale BHO extraction yesterday... It went well :thumbsup: At first I threw a bowl in a pyrex container and was thinking only a few drips would come out... WRONG! Next thing I know I'm pressing the butane to my device and out the bottom comes pouring butane... My bowl gets completely soaked, in butane.. Looks frozen, infact it is.. I'm like oohh no what have I done with my buds??? The bowl that was in there turned into a sticky super crystally looking bowl and below that theres slug looking trails of sticky goo. Yep, it Rating: 5
