1/2 stick of butter and 70g of trim? There's no typo here? Wow... Let me touch on something real fast. Butter has a point of saturation. For example, if you take a glass of water, and begin stirring in teaspoons of sugar one by one, you will eventually reach a point where the sugar will no longer dissolve into the water, but instead, collect at the bottom. The same goes for the butter and THC; there are only so many sites on the fatty molecules for the THC to bind to. And with 70g of trim and only .5 stick of butter, I think you have surpassed this threshold.
Now then, to answer your question, I'm not exactly sure why the butter hasn't hardened. I'll list a few reasons that could cause your problem:
- The temperature of your refrigerator is not cold enough to allow the butter to re-solidify. Lower the temperature of your 'fridge via the dial in the back.
- Your ratio of butter to weed was off. You had so much pot in there that it could have absorbed the butter. Then, (this is a guess) you did not squeeze out the wet pot to collect it.
- Some other agent from the marijuana was pulled out into the water and, due to the butter/weed ratio, will not allow the butter to re-solidify.
Honestly, I would first check the temperature thing. You don't want to freeze the water, but you do need it pretty chilly. If that's not the issue, then I would take the water you have and boil 3/4-1 stick of butter in it for an hour or so. Also, make sure your using regular butter -- not some funky diet stuff, something with 'an added ingredient,' margarine, etc... GL
