Chemical Makeup

Perlite is a naturally occurring volcanic glass that, when heated, expands into a lightweight, porous material.

Typical composition includes:

• Silicon Dioxide (SiOâ‚‚) – ~70–75%
• Aluminium Oxide (Alâ‚‚O₃) – ~12–15%
• Sodium Oxide (Naâ‚‚O) – ~3–4%
• Potassium Oxide (Kâ‚‚O) – ~3–5%
• Iron Oxide (Feâ‚‚O₃) – <1%
• Magnesium Oxide (MgO) – <1%
• Calcium Oxide (CaO) – <1%

This unique mineral structure is what gives perlite its lightweight, airy quality and excellent water-holding capacity.
