I wonder now how much gold dust gets accumulated in the lungs of goldsmiths. I wonder if they take organs to check for sweeps.
Depending on the work, it may also require frequent trips to the hearth for torch work. You really don't want to use an oxy/propane torch in a sealed glovebox.
In short, it's too much hassle and makes the work more difficult and much slower.
I was a jeweler for a couple years and the common practice was to have carpet and a sticky trap at the door. The carpet was torn up every few years and used to throw a company vacation.
You need outside air ventilation.
There is lots of mechanical suction for things like polishing to capture the waste material for post processing.
Most will wear a leather apron for heat / burn protection and capturing fine dust/dirt from polishing compounds. I suppose you could destroy that eventually in a giant smelter.
