I Followed the STB Tek using 500 grams of MHRB and am encountering problems..the dmt formed perfectly in the jars in the freezer except when i pour out the naphtha the dmt in the jar seems to disappear..as of now i am starting to see a yellowish goo on the bottom of the jar.. it has maybe been 10 hours? sense i poured out the naphtha.. Another question is i saw someone posting that with the STB Tek some people only let the bark sit for around a half hour before pulling? Thanks in advance for any help

A great place to start is the FAQ:

Melting/dissapearing crystals after freeze precipitation / Whats the best way to retrieve crystals after freezing?


Post more info if the link does not provide the help you need. Good Luck!
