Is a waxy glass tube.. got it from the vapestore.co.za .. 300-400 rand.. can't remember exactly. Icing sif from pnp (20 bugs) or any other stainless steel, and coffee filters.. fitting your size tube.
Vapestore also has the none stick plates.. highly recommended ^^
If you work fast.. use a bucket of water beside and dip the glass tube in quickly to warm up. If really cold, you angle the gas can, the glass bit connecting the nozzle of the can can chip off. Gets really really cold. ^^ I also use a kitchen towel wrapped around the glass tube to keep my hand warm.
