Julie it is then. BJ is a somewhat unfortunate acronym for your username looking back on it. If you see what I mean
For smoking gear, what I find best is (as far as quick improvised versions go) a pipe made from a test tube. Borosilicate so it won't shatter. Torch the closed end with a propane torch, and make a small air-intake hole with a narrow-gauge point, a cleaned up carbon battery electrode (molten glass doesn't stick to graphite) sharpened to a thin point with a grinder etc.) to provide an air intake. A larger hole made up near the mouthpiece, for a carb/choke, before using a guitar string, coated in finely powdered pencil lead (its a mixture of graphite and a binder clay, afaik, and certainly contains no Pb), a thick bass string is best, the free end threaded through the eyelet, to create a noose, and with pliers, exert a uniform constriction on the heated mouthpiece (open) end of the test tube, to restrict airflow, heating it around the sides first so as to give it a wasp-waist type form. With a decent-size carb that can be used to load in the gear and then a piece of borosilicate glass tubing welded into the neck, and a couple more pieces of boro glass rod, to be used as stand legs, a pair of bipods, made by heating the glass enough to slowly bend it, and coiling it around the test tube as if cutting the bottom off the number '8' glyph and threading the tube through the top loop, a pair of these coiled half-8s, one at either end of the pipe, serving to allow a hot pipe to be rested on a normal temperature surface without burning the surface. The test tube, loaded through the choke with gear, then gently tapped to the bottom closed end can then be heated from below with a lighter flame, or small torch, carefully, whilst inhaling, and the narrowness of the openings, whilst the choke is closed creates a weak partial vacuum, thus lowering the boiling point of the H and allowing it to vaporise at a lower temperature whilst confining the entirety of the generated gear vapor within the test tube so unlike off foil, non gets to escape.
Same design works nicely for smoking ice and other such stimulants (never tested it with crack however) too.
Or for a better alternative to foil, try using an open, empty metal cigar tin, like cafe creme or those tiny shitty hamlet minis come in, after first torching it with a blowlamp to burn off any paint and surface residue, allowing to cool again before handling etc. The V-shape of the point between the flat and the sides can be used to load the gear and then a jetflame lighter to warm the thicker metal, held from a distance, before switching to a regular one, to avoid burning your fingers.
Do make sure to roast the tin clean of paint first, and plastic coatings if any on the inner surface. Works better than foil, which IMO is too unreliable and shitty. for smoking gear.
