Hi. I intend to make (budder) & just checking if this is the proper process. I’m running butane cans through a glass tube into a shallow Pyrex pie dish. I will then do a quick purge & place the Pyrex dish inside my crock pot filled with warm water for 20min, then turn crock pot on to ‘warm’ setting for one hour, until the bubbles have formed to release fumes & transforms into foamy texture. Is this okay?
