Been post processing my rosin for testing using our
7x7" terp sauce plate. I've tried 2 different strains and I feel like the material that budders up rather quickly if not immediately requires a different process than if you have more sappy or runny material.
I pressed out some skunk #1 auto flower at 210F in 160u filter, with a consistency mixture of budder and a shatter. Bud is over 3 months cured in jars. I have to run the PID on the terp plate controller about 20F hotter as my set temp than what I wish to achieve at the base of the jar. This is due in part to how the jars are designed, they don't rest flat like say a beaker would. Unfortunately I dont have any flat glass bottom jars with screw on lids so it is what it is, no matter, it all works the same so long as you know your jar floor temp. I chose a PID temp of 160F to achieve about 140F on the jar, this temp was needed to melt the rosin, and it melted very, very slowly. Temps will vary based on material. The higher temps will decarboxylate your oil faster, so it pays to be mindful of the time.
The rosin started off in a 0.84g ball, pretty hard, I guess pull and snap consistency with the emphasis more on snap. Sorry I didnt get a pre-picture, but it looked like a little cloudy ball of glass, definitely not a crystalline type consistency. I put the ball of rosin in the middle of the jar and tightened the cap then onto the sauce plate.
After about 5 hours on the plate, it was time for bed so I took it off to avoid it fully decarboxylating while I slept. This morning I opened the jar for the first time to get a look. So far this is looking a lot like it just muffined up sort of like what BHO does while in a vacuum. Those spots on the bottom look like crystals and there may be there but those large voids appear to be air bubbles. I haven't stirred it as I want to see how long it takes to decarboxylate so will run it again for part 2 this afternoon while I can babysit it.
The consistency has definitely changed, the jar still smells stinky so I guess I'll have to have a dab towards the end of this experiment before it's decarb'd then again after. Color hasn't changed much.
