Perlite is an amorphous volcanic glass that has a relatively high water content. It is a mineral that appears in nature and has the rare property of expanding greatly when heated sufficiently.
When it reaches temperatures of 850 – 900 °C, the perlite softens. The water trapped in the structure of the material escapes and vaporizes, causing its expansion. The expanded material is a bright white color due to the reflectivity of the trapped bubbles.
