Is a teacup a insultaor or a conductor?

A teacup is primarily an insulator. Most teacups are made from materials like ceramic, porcelain, or glass, which do not conduct heat well. This property helps keep the tea hot while preventing the heat from transferring to the outside of the cup, making it safe to hold. However, if a teacup has a metal component, that part could act as a conductor for heat.
