Has anyone tried putting colored mica powder in there PC? I don't PC yet, but if it worked, I'm thinking it might come out a bit like metal flake paint?

Don't know about mica, but graphite kills the static charge.

I have used metallic PC on some boolits and it comes out as pretty as you can imagine. Powder was from Prismatic though.

Didn't think about it killing the static, very good point. I know they use colored mica powder for makeup, so I just guessed it would work. I use mica powder on my tumble lube bullets and it gets rid of almost all the smoke, and no more sticky seating die.

I'd look at what happens to mica when subjected to heat.

What effect am I to be looking for? Casters have used mica for many years in reloading cast bullets, so I'm not sure what you are referring to? Please enlighten me.

I believe the Eisen glass viewing windows in oil stoves, that allowed a person to see the fire, were made of mica. I think it was just layers of mica, but not 100% sure about that.

Lots of old stove, fireplace, etc, windows or viewing ports were mica. Old lanterns and lamps had "globes" that were thin sheet metal frames with mica panels. I collect and restore old lanterns, lamps, stoves and other gas pressure appliances and i have some of these still with an original or period correct replacement mica shades. Glass ones are globes, mica variants are called shades. It was the best thing they had back then to resist high heat since mica is a mineral. They advent of borosilicate glass had not made it's way around yet.

I just read that it was called Muscovy Glass made from Muscovite mica. Another form of mica it said remains stable to 1650 F. I was wrong about it being Eisen glass.

Awesome! I learned something today! Didn't know it was used to make glass.

When I was using alox on bullets I would dust them with mica to take care of them being tacky or gummy.

The mica lamp & lantern shades snd stove windows were not a hard "glass". Pretty sure its raw sliced/polished mica sheet. Its actually flexible and easy to put your finger through if you pushed on it to hard. When it is broken you can see the flakey, thin layers mica naturally has.
