I'm posting for a friend. He has been using Nomans tek for the 5th time. He is very pleased with this tek and feels his last pull of 1.5 grams from 250 was exceptional. He has still been using the ammonia wash with no issues and has done a heptane recrystilization. The product of 1 gram of pure crystal from first two pulls and .5 from 3 and 4 has a tint of yellow, but appears outstanding. His technique with the dab hot plate has produced multiple break throughs from previous batch. Now for the problem. Applying same vaporizing technique to this new batch was such a disappointment. My question is, can he be heating the plate up to much? this hasn't been an issue in the past at all. The previous batch was pretty grainy like sand, kinda brown and had been sitting around for over a year. This batch is fresh, white, fluffy crystal. Could it be more sensitive to heat? Could this spice that appears to be exceptional be a dud? Both extractions came from the same plant matter, using the same technique. Any advice would be great.
Thanks
