SteveM:
Great information.Thanks.
I seem to remember my parents using mica snowflakes on our Christmas tree in the 50's.
Only reason I mentioned mica, was that I seemed to remember it having been implicated in pneumoconiosis(miners lung) and there are safety limits for exposure to it in industries where it's used or mined.

http://www.nohsc.gov.au/OHSInformation/Databases/ExposureStandards/az/Mica.htm

 "The Exposure Standards Working Group recommends a time-weighted average exposure standard of 2.5mg/m3 (inspirable dust) for mica containing less than 1% quartz. This exposure standard is based on its historical use in Australia; and should provide sufficient margin of safety in controlling pneumoconiosis and other respiratory effects"
