Well... though isopropyl alcohol is not the better choice for making hash oil (as its somewhat hard to evaporate), it works too... i would sugest to simmer it in a water bath (see the Green Dragon recipe), to make the extraction WAY faster.
The alcohol will be ready to be evaporated when it become dark brown/green. As darker, as better.
A frisbee can be a nice place to evaporate it... but i would prefer a shallow glass dish. The hash oil is EXTREMELY sticky, and is far easier scrape it from glass than from plastic. When you were to scrap the hash oil, put some warm water into the dish. The water makes the hash oil to stick less to the glass.
I store it in a small plastic box. But any place with smooth internal surfaces (for avoid the hash oil stick too much) is good.
Any questions, just ask! And good luck! :thumbsup:
