I'm slowly getting ready to make some BHO and have two jar related questions.
The first is can I blast directly into a jar like this or would the cold butane cause too much thermal stress, or am I overthinking things?
Secondly I'd like to pull a vaccuum in the same jar using the water hose vaccuum method.
I have no idea how strong of a vaccuum that can even create, perhaps anyone here has done this before and knows if the glass would hold up?
