Use a double boiler type setup so you do not burn anything.
at the moment i have grinded up bud in a small glass jar and covered it with 100% vegetable glycerin. i will give it a rigorous shake daily and let it sit for a really long time. i will probably not strain it but just leave it until all the glycerin is used up. since this process will take a couple months i plan on trying it with alcohol. only concern with alcohol is how i am going to cook off the alcohol safely. is it possible to just use a stainless steel saucepan and cook it on low heat and let it simmer with the fan on high? also why does rick simpson add few drops of water towards end of cooking?
