This is part two of a multi part tip on
sorting glass frit. Click here to go to part one.
One of the major concerns with
making and sorting glass frit is doing so safely and without
inhaling potentially hazardous silica particles. Even if you
don't see the particles, sifting can make them airborne and they can
be inhaled without realizing it.
Avoiding this is essential.
Short term exposure to glass dust can cause coughing or temporary
respiratory irritation, especially in sensitive individuals.
Even worse, long term exposure to silica particles can cause
silicosis, a serious lung condition that can be fatal.
To prevent this, it's important
to take steps to minimize the change of inhaling silica dust.
One possibility is to wear a respirator when sifting glass frit.
The best respirator would be one with a P100 filter, which would
filter out virtually all of the potentially hazardous particles.
Another option is not to sift
the glass frit when it is dry. Instead, wet the particles with
water. Damp glass can still be sorted, and the frit will air
dry in a day or so.
