There is a lot of good stuff today on the list....but for now, I will just
post a resource for mica powder... You might try Daniel Smith Art Supplies
http://danielsmith.org/
Twin Rocker and Carriage House paper supplies also carry mica powder
pigments.
I certainly had and interesting day today.....wish I could tell you about
it (smile)...Maybe will tell my Getty II folks some -- Just got done
discussing the ironies with my hubby -- we had a laugh or two.
