is that because your mason jars are tiny and pull a serious vacuum, whereas my 3 gallon chamber is quite a bit more volume? ive let my pump run for an hour before. no difference. cant get past 26.5 - 27" or so at 2200" 660 meters.
i have actually not been able to muffin some material, rarely though.. most of it muffins.. i feel when i dont muffin it enough, thats where i fail..
do smaller runs man, learn. it is really difficult, unless you know what you are doing, or unless you have the same exact material to work with time after time..
IMPORTANT, THIS IS A LEARNING TUTORIAL.. NOT REC EVERY-TIME, -would probably take too much effort..
i would start from scratch, do a 1 tube run, and dont waste time, spray, dry, vacuum (no heat) achieve muffin.. you must achieve muffin. no heat... then melt, (outside of your chamber should be no higher than 135-45 on melt.. just melt shit slow, it will eventually pool up.. once it does, kill heat pad.. turn vacuum to full pump, hopefully you will see shit puff up fast then deflate... get your oil(temp of actual oil in chamber) to 100 degrees F and start full vacuum... vacuum till you see bubbles very very veryyy slowly coming out... then raise temp to 110 degrees F.. full vac.. vac for a longgg time.. id say raise 7 degree F ever 3-5 hours from there. til you get wax... i hope it works for you, and anyone trying.. us who already know how to make it try to speed it up, we all probably have wasted much time learning and failing.. keep trying/tweaking this process till you achieve, then once you do, play it safe.. all foreign material is tricky IMO.. unless is ultra fresh and dank.. those tend to just work...
i think it is possible to make wax out of any material.. the first time i EVER made wax, i was working with extremeleyyyyyy old material.. but it waxed up, fell asleep desiccator got to an extreme heat, vacuum was running all night, wax was bone dry.. .. made me think i was boss.. have failed many times since then.. but! like ive mentioned millions of time son here, each material has a different process..
gonna try a run tonight!
