Aluminum foil doesn't melt when crackheads smoke their shit on it but they end up with lots of Al in their lungs so is Al an exception to the rule or does the rule need more research?
I have no clue whether toking oil as you describe with SS wool is harmful or not but it doesn't sound like a great thing to do just in case.
I like to cook my pot up in coconut oil and eat it. I gotta save what lungs I got left for my coffin nails.
The rules regarding a phase change of any substance from solid, to liquid, to gas form are not subject to interpretation.You can research further the concept of the three forms that matter can achieve however trying to discover a substance like aluminum that does not follow the rules will be in vain.
You quote another myth about aluminum, citing crack heads. I am certain from your post that you are not a crackhead.
Do you know where the myth that smoking out of aluminum will hurt you came came from? It started when it was reported that the plaque found in tthe brains of Alzheimer patients contained high levels of aluminum. Even among scientific peers the conclusion that excessive aluminum was even present is hotly debated but even if it was true, then you would have to reveal a way for the aluminum to enter the body. If you heated the aluminum up past its boiling point then it would need to remain at that temperature until it was inside you body.
Do you have any idea what kind of burns whould happen to you if you inhaled any gas at all that was at the temperature needed to keep aluminum gaseous? Lolz, you would indeed have a major healh problem on your hand, but not to worry my friend because unless you have a machine designed to weld aluminum then it just aint gonna happen.
As a kid a popular and harsh way to smoke in a pinch was to dent a beer can and put holes in the dent. Voila! A pipe at a kegger! It is possible to melt aluminum this way and wear out your beer can pipe, but even oxidation which is not necessarily boiling the substance would only produce at worse aluminum oxide. I use aluminum oxide in a wide range of techniques to purify extract because it is a well known chromatographic stationary phase. I do not worry if any alumina gets into the extract because it is non toxic to humans and it too needs thousands of degrees to become vapor.
I suggest you stick with using cannabis the way you are most comfortable, but I reject arguments made based on irrational and unsubstantiated fear generally focused around an unseen gas or unseen/unfelt and unknowable fatal risk. If smoking out of metal killed you then a WHOLE lot of people would be dead right now. Put simply, these are myths.
