Glass is a conductor, so it allows heat to go through it (Ex. Touching a pie pan that came right out of the oven)

Rubber is an insulator, so heat has a hard time passing through (Ex. Using a rubber grip on a cast iron pan.

Cloth is also an insulator, so heat has a hard time passing through (Ex. Using a pot holder to prevent the counter from getting scarred)

Wood is also an insulator, so heat has a hard time passing through (Ex. Bedding for a rabbit hutch)
