Thanks for the specific details used in your process. I have a suggestion and would like your opinion.

What if you could just extract all the oil from hash without adding any chemicals. I have seen the butane process and have smoked both that type of oil as well as most of the ones made by other processes available at the dispensaries. Some folks are making good oil out there but they are still chemically processed. I know that folks are making oil out of their trim without making hash out of it first. I was thinking of using bubble hash but may be able to use trim as well.

The oil produced this way may contain some water but it should not contain the chloryphyl and wax impurities you described above and should be relatively easy to remove. It will definitely not contain any hexane, butane or any of the alcohols you mentioned.

What problems might there be with oil that is squeezed directly out of the hash or buds.
