I can assure you that even if I left it on for 30 seconds more it still would not burn to a point of potency loss. It mostly little remnants from previous scrapings which I've tested by fully scraping the remainder from 20+ uses and it was WELL below 5mg.

It's kinda an odd thing to say, I've done this over 100 times and I've smoked crystals about 40 times. I've tested the potency of 'x'mg of crystal and 'x'mg of goo as well as telling slow evaporation vs fast evaporation and the very clear conclusion is that there is nothing noticeably different about fast evaporation. Thus I will not invest a whole bunch of money that I do not have on an expensive food dehydrator :/

Sorry for the rant but people stating opinions as facts is a pet peave of mine.
