Do you have a link for the butane blast.
If you google "bho" or look in the concentrates section of this site you`ll find it, I just assume everyone has heard of BHO, budder, wax, shatter and so on now days
There`s loads of extractors you can buy, there normally glass, metal or some kinda fancy medical grade plastic, you stuff the tube with dry plant matter, then put the filter over one end and the top has a hole to push a tin of butane into (getting a clean zero impurities butane gas is key to getting a nice clean end product)
you blast that into a pyrex glass dish and then after that use heat or a vacuum chamber to purge it
It`s a lot less hassle then bubble bags or ice or dry ice hash and I`ve never seen a bubble has you could dab, when it comes to herb I`m a vape man I won`t go over 200c but with BHO extracts as there is almost zero plant fibers I`m fine with dabbing that oil right on a glowing quartz nail makes the most tasty vapour
If you have any problems with finding a method or tools locally I`ll be happy to give you some advice man but like most of this kinda stuff what you can get and how you can use it depends on where you live and what kinda area/environment you have to work in
