Turn the cap until the internal pressure is released, then retighten. Near then end of the Dimond growth you will need to vent the jar more often and for longer period of time.
you could probably kick that up to 1 time daily or more if you had a more controllable way to release the pressure.
ideally if you could release small increments of solvent it would be a more gentle transition tward supersaturation.
Yep. I still would prefer jars over miners for the cost and space that miners cost and I sell them
I think if your fire marshal is breathing down your neck or your tired of jar inconsistency. Then grab a miner, but there isn’t really any better crystallization in a miner than a jar
I don’t think I will buy a diamond miner due to the size issue, jars will fit in the small freezer compartment of my fridge and also help me learn the tek
if the freezer compartment in your EXPLOSION PROOF refrigerator happens to be large enough to fit a canning jar full of flammable solvent, then by all means include a cold crash at -20C, but the fact is you A) don’t need a cold crash B) would generally go colder C) can get colder simply using evaporative cooling (pour early).
note: pouring with too much solvent (undersaturated) isn’t particularly safe even in an appropriately rated hood or booth. I’m guessing you have neither. So I suggest ignoring option C. If you insist of cold crashing, use dry-ice and a cooler, and don’t do it inside.
I said -20C was NOT cold enough. So in addition to being an explosion risk, the freezer in your fridge was insufficient.
Read it again…
As fas as why?
Not sure, but my best guess is that for the vast majority it’s because that’s how they tried it, and it worked, and they wouldn’t know experimental design if it bit them in the face…their ability to optimize the process is therefore severely limited.
