Are there some tricks or basic practices to minimizing toxic dust kicking up
when mixing
powders in 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 and a mask. p.s. I posted this yesterday
but the list appears to have been down.
