Thanks landfishd, yes I would love to see some pix of your powder. Sounds like you are purging butane correctly, there are lots of methods, and you are also correct that many people, especially ones supplying MMJ coops in SoCal do not purge the butane properly. So sad as many patients do not know any better and are not getting the full health benefits from their medicine. Stainless steel is a good metal for use in butane honey oil, but not galvanized or copper. So many idiots use plastic and PVC, especially on YouTube, it makes my heart sad that they are passing along these bad and unhealthy habits to others about medicine that has so many positive uses.
Peace
