Can I add glitter to this?

I've used 325 with glitter pigments, and it works very well. You'll have to add a decent amount of glitter and it will take longer to cure.

Can I use this to cast a dome-shaped mask using a silicone mold? Will it stay liquid long enough for me to tilt it back & forth to form an even coat?

Smooth-Cast 300 is a snap cure material - a better choice may be Smooth-Cast 325 or Smooth-Cast 65D, both of which have a gradual cure profile.

Yeah, to an extent. I’ve taken a dremle tool to casted plastic to sand down parts and remove unwanted flashing that occurs. It’s pretty tough stuff, let it cure for a day or two before sanding or working on thinner areas, but I’ve even taken a hacksaw to some castings and they have held up just fine.

Is this a silicone or a urethane?

This is a urethane casting resin.
