When considered as the temperature of the reverse change, it is referred to as the freezing point. For example, the melting point of the element mercury is 234.32 kelvins (−38.83 °C or −37.89 °F). Certain materials, such as glass, may harden without crystalizing; this is called an amorphous solid.
The material with the highest known melting point at atmospheric pressure is graphite, with a melting point of 3948 kelvins.
