Thermal insulators are things designed to not conduct heat, or conduct heat at as slow a rate as possible. Oven mitts are thermal insulators, for example.

A thermal insulator is a material that doesn't readily transfer heat. Materials like Fiberglass, Lexan, Rubber are all good insulating materials (i use them in the lab to keep the motors running on heat run from using the test fixture as a heat sink).
Materials made of metal are not good insulators, as mentioned above, metal will act as a heat sink and actually draw heat away from a source. Which is why if you've ever seen the cooling apparatus on a CPU, you'll notice large aluminum fins over the processor. Aluminum is highly conductive of heat, and transfers heat very well.

No. Glass and plastic tend to heat up very quickly and in some cases, plastic may melt if put in extremely hot temperatures. If it does not require boiling something or melting something, I would suggest to use a Styrofoam cup to hold a hot liquid, as it was made for that purpose. Since you can't use Styrofoam, you could use a thermos, which uses a vacuum to insulate the contents. Otherwise, use the glass, it's your best shot.
