I just got done taking my crystals out of the tray from freeze precipitation, and the first thing that I was ecstatic about was the fact they didn't melt. The previous times I attempted extraction I was never able to actually remove the crystals from the tray without them melting due to a variety of issues. On my previous extractions I used 420g MHRB and a drain cleaner containing potassium hydroxide. Melting issues aside, this time with 60g lime and 100g MHRB presented me with exponentially more crystals. I then used Ronsonol lighter fluid for freeze precipitation. When they were done, I tilted the tray in the freezer for a few hours, then moved it to the fridge, and finally moved them out of the fridge to remove them just now. They're absolutely beautiful white N,N crystals, and I'd really like to thank Q2121. Your tek was invaluable as well as your help along the way. I poured the lighter fluid back in with the bark, mixed it up, put it in the tray, and back in the freezer it went. Still haven't had a chance to try any, but I'll let you know how it goes soon.
