Theses variations can apply to the use of a small bubbler pipes, bong-style bubblers, or improvised bubblers, though smaller bubblers are often found most preferable. The water in the bubbler acts only as a heat-sink and will not absorb a significant, if any, amount of product, as the freebase product is not very soluble in water; however, the use of ice in cooling should be forgone, as it may cause the premature precipitation of product within the chamber.

This design differs from "the machine" slightly in that it does not consistently protect the product from open flame.

  1. Prepare a plug made of metal mesh by cutting a piece of an excess of the appropriate size to fit in the bowl.
    • stainless steel and copper of a coarse mesh are preferable, as they do not tend to burn at the temperatures needed for vaporization.
    • a thin tube of about an inch long will facilitate the most effective use
  2. Using pliers to hold the cutting, use a torch to thoroughly burn off any machine oil or coatings found on the mesh.
    • perform this step until no more smoke can be observed emanating from the cutting.
  3. Allow to cool and roll the cutting tight enough to fit in the bowl.
    • if using a small thin tube of mesh, stuff the end tightly in the bowl and coil loosely around the inside, leaving about a quarter inch of space between the coil and the lip.
    • the plug needs to be tight enough to suspend it in the opening but not so tight as to block air passage.

Use of the variation pictured is often found to result in runoff down the stem of the bowl, which is only retrievable by cleaning the bowl, and it is also found difficult to prevent the burning of product due to exposure. However, many of these potential problems are avoidable by mastery of heating and calibration of airflow through the piece, and by use of the coil method noted above.
Notes on Administration
  • To load, simply place a measured dose directly on top of the plug and carefully melt into the plug by feathering with a flame or other heat source.
  • Though a standard lighter will work for vaporizing if used carefully, a torch may ensure a fuller dose--though at a slightly higher risk for overheating and burning if any spice remains on the surface.

A design of bubbler or piece that facilitates being angled in such a way that the product can only run down toward the heat-source is preferable to ensure full dosage.

  1. Prepare a glass piece to be fitted to the intake of a bubbler.
    • this can be accomplished either by using a glass piece small enough to fit inside with a gasket fitted to provide a seal or by attaching the piece with a small section of tubing; traditionally, a dropper stem with the nozzle broken off and edges melted is implemented.
  2. Cut off a piece of the metal scrub pad, hold it with pliers, and burn with a torch under an oven hood until no more smoke is emitted.
  3. After it has cooled, stuff it in the larger end of the piece, and stuff it down toward the end designated for heat application somewhat tightly, and so that a part of the mesh is exposed.
NOTE Information.png
Most designs will result in runoff if used at a downward angle, but if a straight glass piece is used, that runoff may be immediately retrievable for further administration by simply plunging the plug to one end of the piece--collecting oil--then back into place.
Notes on Administration
  • To load, simply place a measured dose inside the piece and onto the plug, and carefully melt into the plug by feathering with a flame or other heat source.
  • A butane torch is a preferable heat source for the operation of this piece.
