Qwiso Purging Tips

Looking for some tips/advice.

I like to make QWISO and then convert it into an e-juice form for smoking but whenever i make QWISO i feel/taste like im not getting all of the ISO out. Different strains, but always has the same taste which seems like iso.

My process -
- freeze all product/iso 12-24hrs
- 20sec washes ( 2 washes per jar/plant matter) - usually 7gs at most in a wash
- strained thru unbleached filters into pyrex.
- Then pending my time needed, ill either let it sit out over night with a fan and evap, or ill aid the evap with a hot griddle/water bath until all liquids are gone and left with oil.
- Then i scrape pans and pile all into Parch paper. work it together and flatten out thin as much as possible. then set the parch paper inside my empty pyrex on the griddle and "purge" until i see bubble start forming.

Am i doing it correctly? Do i need to let it bubble when i purge? I thought the bubbling was co2 being released which was bad and degrading to the oils. maybe im wrong. From all the reading ive done tons of people just say once its evap'd, its all out of iso. I still think some iso is trapped into the oils it self somehow.

Any advice/tips to help rid that taste would be great. its not a huge concern but it does seem like it makes the hit a bit harsher in the back of the throat, causing coughing sometimes.

Thanks in advance!

If your concerned just keep doing what your doing.. i would maybe do a double boil just to keep from getting too hot but it is hot enough..

I think i know the taste your referring to and its not going away

Odd, i do it pretty much the same way but it taste like weed from a vaporizor for me. It comes out dark yellow but not exactly shatter and i believe its because i have been using 91%. I dont get much cough out of it either, nothing like a dab. Maybe its the strain.

Thanks for the reply guys. guess i am doing it okay. i guess ill try purging a little longer. Its nothing bad but deff noticeable.

Ive been currently mixing the concentrates with ejuice mixture to make it liquidized and able to smoke in a ejuice style vape. works out amazing.

You should let it go until the bubbles cease or slow dramatically. This is also why I use ehtanol, because even if I don't get a full purge it is no big deal.

Thanks. i always thought the bubbling was bad and degrading. should have some stuff ready to finish purging tonite and ill test out.

Ive been thinking of going to ethanol(everclear) aswell since i can only get 91% iso here.

I never get bubbles..

There are lots of people who make great stuff with 91

Hrm interesting. I did another run last nite that evaped for about 36hrs. scrapped and purged. 1.2g of oil. still had some bubbling going on at 180* which i figure is some iso bubbling out. It does have a better smell now that i did a full 20mins and looks alot better then my usual runs.
