Are there some tricks or basic practices to minimizing toxic dust kicking up
when mixing powders into solution? I'm putting together my first cyanotype
and gum kits so
I guess the main ones I'm concerned about are the ammonium and potassium
dichromates. I'll be wearing gloves, goggles and a mask. I was also
wondering if anyone has ever used a "pill crusher" rather than a mortar and
pestle for grinding crystals?
