Metal bulges

Metal drifters are shaping and processing tools, mostly made of brass , as they can be manufactured and soldered easily and cheaply. They are used in glass blowing to create the basic shapes.

So that the brass does not get stuck on the hot glass during processing, the expansions are always wetted with wax . A wooden handle protects against the good heat conduction of the metal.

Alternatively, there are also shaping tools made of graphite , as this material can be shaped very well by sawing, milling and turning and it can withstand well over 1000 ° C.
