Well... today i tried it again, with bad results... i only went barely high... even if the hash oil were good.
I tried to make a stronger tincture, so i used 0.17 cm3 of hash oil and added about 4 cm3 of alcohol. I heated it in the boiling water to evaporate some alcohol and make the solution stronger. The remaining volume of alcohol, after heating, was about 2 cm3.
Then i added about 1.5 cm3 of glicerin, mixed well, and heated again, for evaporating the remaining alcohol. This time, the amount of tar-like substance produced was much greater. After some 30 minutes of heating, the volume of the solution was about 2.7 cm3.
I separated the solution, and as i had read that not all THC went to the glicerin, but some remained in this tar-like thing, even if the process were perfectly done (as the rate of thc in the resin/glicerin is a chemical constant.), i also colected this tar-like thing. As after taking the glicerin from the test-tube, most of the tar was glued to the walls of the test tube, i scraped it from there. After cooled, it was almost equal to the original hash oil, only softer.
I tried this tincture, and had only mild effects. The rhymes i did write in the lounge were the only result of the tincture. I were slightly stoned, but only it.
BUT... yes... now is the best part. After realizing the high wouldnt increase anymore, i smoked the resin i has scraped. And went HIGHH. Of course, the amount i smoked was FAR greater than i smoke usually, as for making this tincture the amount needed is greater, but the effects were FAR greater also... so, i could conclude that this time most of THC had remained in the tar-like oil, and only a small amount of it went to the glicerin.

As the only difference between the process i did today to what i did yesterday was the concentration of the solution of hash oil in alcohol, i must conclude that it was the cause. So, next time i will try with more alcohol, like i did previously.

And well... at least im stoned! :thumbsup::stoned::rastasmoke:
