yes it will work. the heat is only used to speed up the process. they sell 90 somthing% right next to the 70 in my wallmart. Make sure you use somthing that is easy to scrape like a glass dish that is large enough to fit a stright razor in or it will be difficult to obtain the resulting oil. Just leave it in an open area and wait. you can use a fan to help the process along as well.
Left Reviewed by Left on . question about making hash-oil i know the method of making oil where you mix isopropol alcohol with bud and then boil it off to leave you with oil. is it possible to accomplish the same thing without using heat, but just allowing the alcohol to evaporate over a longer period of time?
