Beryllium metal is an electrical and thermal conductor. Beryllia, the ceramic of beryllium, is a thermal conductor and an electrical insulator. Both have very high thermal conductivity relative to other metals or oxides.
Insulator
No. Ceramic is a bad conductor of heat and electricity.
A material that is a good thermal conductor would hold in a lot of heat. These thermal conductors would also transfer heat easily.
Carbon and Sulfur are both elements that satisfy your query. There are several others, including many gases.

an insulator
Perhaps because the glass is in amorphous structure and ceramic is in crystalline structure. Glass is a better conductor of heat than ceramic is.
A cup made of metal
Mica is both an electrical conductor as well as a good thermal conductor. Block mica is used primarily in electronic equipment.
Beryllium metal is an electrical and thermal conductor. Beryllia, the ceramic of beryllium, is a thermal conductor and an electrical insulator. Both have very high thermal conductivity relative to other metals or oxides.
Why is glass a good conductor of heat and ceramic is not a good conductor of heat?
Neither, I would drink it from a ceramic mug.
Yes ceramic is a good thermal insulator being bad conductor of heat. For this reason it is being used in the furnaces to contain high temperature.
It depends on what you compare it to. Steel has a thermal conductivity about 100 times greater than insulation, but is less conductive than materials such as ceramic or copper.
Wood is a thermal insulator. It is a poor conductor of heat.
The thermal conductivity of a perfect conductor is 1
