Our premium volcanic lava rock ranges in colour from deep black to reddish-brown. Its porous structure makes it perfect for aquarium filtration, providing ample surface area for beneficial bacteria to colonise. Excellent for gas grills, fire pits, and fireplaces. Unlike charcoal, lava rock is durable and does not burn away. It glows like charcoal and enhances the flavour of food by vaporising drips, giving it a distinctive char-grilled taste.
