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.

 "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"
