You are absolutely correct. My students use the black crack glaze
sparingly and are very careful of any dust in the studio. If anyone
uses that glaze as a stain, they wear gloves.

I think the same caution should be used with any heavy metal, like
cobalt or chrome and iron glazes also. They always wear a filter mask =3D
and do not make
billowing clouds of dust when removing the glaze with a nylon pad or
even when using a metal or rubber rib to remove the glaze from the high
spots. I have then do that with the piece in the large spray both so any
dust is drawn away from them. Then wipe off the piece with a large
sponge.
This made me think about fritted low fire glazes. They are in the same
category in my opinion as frits are basically ground glass and could
harm one ( any dust) if the breathed the dust long enough over time.
Are you coming to NCECA? If so I'll see you then.

Thanks Bill,
Most glazes and clays have silica in them so it's always a good idea
to avoid any dust in the air we breath.
I will be there - hope to see you.
