Why Perlite Works. Genesis in Fire Rapidly heating perlite ore to temperatures of about 900°C (1,700°F) softens the volcanic glass causing entrapped water molecules in the rock to turn to steam and expand the particles like popcorn. The expanded particles that result are actually clusters of minute, lightweight, insulating, glass bubbles.
