Could you describe how you did it? Maybe someone can point out what was wrong... as it always works for me... with awesome results!

BTW, i was reading some recipes for making glicerin-based tinctures, but they took a LOT of time... so i thought about a way for making it faster.
First, make some hash oil, or honey oil. It takes some 2-3 days...
Then, dissolve the hash oil in alcohol (everclear).
Mix this alcohol with the glicerin.
Heat this misture until the alcohol evaporate. Doing so, the THC will remain solved in the glicerin.
If you start with the hash oil, the amount of time required must be of a few hours, or less, instead the months of the original recipe.

BUT its only an idea, and i dont know if it will actually work... I will try it right now... if it works, i will post at monday (as i only will enter in internet again after this weekend).
