I looked through the archives and the old archives for an answer to this question and didn't find one.
Did anyone ever gget a definitive answer as to whether micas are food safe or not? I'm playing with PearlEx micas and want to know if they're food safe, so I can label them properly.
Thanks -

Both Aluminum and potassium silicate (mica) and titanium dioxide (colorant) are listed on the FDA's GRAS (Generally Recognized As Safe) list, and
"...may be safely used as colorants in the manufacture of articles or components of articles intended for use in producing, manufacturing, packing,
processing, preparing, treating, packaging, transporting, or holding food,..."
See US Code of Federal Regulations 21CFR178.3297

ps: the FDA doesn't approve every application of every material. They have their GRAS list and specifically list applications that they are requested to approve. In this case, it's mica in contact with food and being used in a polymer based material. If you dig into the CFR, you'll find other approved applications for mica such as a colorant for contact lenses (direct wet body contact).
