I can assure you that -15 to -20 in vac oven ,70-80f and time the vac will pull the water out…ppl say don’t go over that so I don’t, mine come out Perfectly Everytime,(if not then I would ask is it dewax?)… Your terps will not go anywhere, as long as your controlled about it, how do you think these guys sell terps? They clean just like I told you, separation makes it easier…as far the Diamonds… They shouldn’t sizzle, sounds like they need more time in oven no vac,80-85f… You can pull full vac to be quicker but it may ruin some clarity of the stones when stuck Tane pops out, and if to large they may have to be busted down to smaller chunks before throwing in the vac oven no vac,or controlled vac chamber with precise temp controlled heating pad… I always noticed if stones sizzle they need more time… If that doesn’t fix than a more controlled growth will give you the solid structure you need!
As far rosin…I was under impression ,it is what it is… You do anything else and it’s no longer the whole “rosin” idea… Does your dried and cured rosin do this?
