|The hypothetical reconstruction is based upon written descriptions|
and one surviving illustration. A vertical brass pump provides air
pressure via a bronze-bound leather hose to the main tank
consisting of two pieces of copper sheeting soldered together.
Underneath is a small brazier and a pair of bellows. Another hose
takes the heated liquid to the nozzle.
