Although I certainly agree with all you have to say about personal
responsibility, I would say that the dust particles that are
problematic are those below 5 microns in size. These are much much
more likely to be present in the materials we use in the pottery, that
have been crushed heavily, than ordinary 'dirt'.

Unfortunately these particles also don't settle out hours and hours,
and are practically invisible.
