I used some good hash, US made,
for oil extraction using Everclear,
70% net oil yield (crumbled hash added to 45f ref temp let sit 4-5 hrs in fridge) strained in coffee filter & evaporated alcohol in Pyrex using a fan, window open. Very tasty & potent. Below is how I mixed & vaped iT, same as my Blk & Gold oils (Interesting enough the hash oil was more of a reddish color).
I like 2 diff kinds of oil Black and Gold. If u have int this is what I do:
1) Blk Oil: 1 oz herb to 20 oz everclear rm temp let it mix ~20 min, drain& strain into lg Pyrex, let it sit in sun (cover with cheese cloth)
for 20 min & alchemy occurs “green is gone”, makes 5.6 Gr Black oil, no I don’t Dewinterize...but u can if u want.
(NO HEAT used until down to 2 oz liquid in small 2x2 empty Pinzey spice jar
place on coffee warmer until All micro bubbles gone, stir with toothpic!) This oil works just fine mixed 5:2.5 ratio In C Cell cartimizer 2mm oil feed holes for vaping).
2) Gold Oil: Same as above, but use 5 lb of Dry Ice in a med size cooler
Prepare herb in glass jar & 20 oz Everclear in separate jar, when temp = minus -45f immediately mix the 2 &
shut cooler up...lightly shake cooler every 4 min., after 20 min done, drain & strain sitting in closed cooler.
Now just evaporate using fan blowing over cheese cloth cover Pyrex dish, finish off like above on coffee warmer. Yummy
I’ve tried a number of different solvents & emulsifiers(Puff Magic is my favorite did not like MCT oil & this is the way for me).
C Cell with 4-2 mm oil feed holes the way to go for vaping Amazon 2.50–3.5 ea 5 pacs usually.
Also 4 volt vape Pin 3 for $18 no ship fee Amazon... just takes some searching DH Gate for bulk buys.
( usually the 4 volt pins have 3 variable voltages & pre-heat, I don’t use preheat I think the 4 volt setting
just fine). I also use Puff Magic as a oil emulsifier, did not like MCT oil & terps r expensive.
I like 5:2.5 ratio
(Oil to Emulsifier)
I could go on & on, this is all new to me as well past year, just got tired of smoke in my lungs.
Teflon spatulas make best stir sticks & toothpic for stirring oil in Penzey Spice Jar (I save the jars when the wife is done using the spice). Absolute perfect size & thickness.
Put some oil on end of a safety pin & light iT as final check that all alcohol is evaporated u should not see any sizzle just melt...!
vapes well for me- about 45-55 hits per .5 mm cart. fill (1 oz herb will make enough oil for about 14 fills Blk oil, & 10 with gold oil or more if u want to lower the potency.)
As mentioned I use the 4 volt vape pin setting. Occasionally clean the draw tube with a pipe cleaner cut to 1 inch, appears these ceramic oil absorption takes in more than can handle-probably why I don’t use preheat function & draw soft !
Isn’t life grand, hope i didn’t bore u contact me any time.
