I've made my first STB extraction and got 2.44g of white flakes out of 260g of MHRB (and I think there's still some more to come, I'll let some naphta during a month or so for the last pull) ! It was fun and instructive..the two tricky parts were to separate the layers and to collect the crystals.
A good separation tool ready to use (trying to glue two syringe is not that easy..) is a must as are small squares jars with straight edge : it's much easier to collect the DMT in the coffee filter than scrape it when it's dried in the jars.
I wanted to say thank you to all of you, contributors of the nexian community !
