Dear Jewelry/Metalwork artist:
I make jewelry using metal and plastics(plexiglass, acrylite). Many
times I encounter metal or plastic dust. Sometimes I even come in
contact with plaster investment (used for casting) which contains
gypsum, silica, and cristobalite. If possible, I would like to use
the mask for metal soldering. Can you please recommend a mask or
masks for these purposes? I do not have the proper vents for my
studio except for one window. Thank you for your time.
Sincerely,
Dawn
