Lava Stones are pumice formed by the froth of molton rock in volcanoes. Light weight and excellent insulation properties makes them widely used in construction and similar applications.
In Chimeneas, Lava Stones protect the base from the hottest part of the fire, reducing thermal shock and cracking. Use in the bottom of clay chimeneas to prevent the hottest part of the fire touching the clay. Suitable for any clay chimeneas. One bag is enough for one chimenea. Can be used time and time again. Does not burn. Easy to use. Just place the contents of one bag directly on the clay in the bottom of the chimenea and build your fire on top.
The lighter the lava, the better the grade quality. So don’t be fooled by the weight. We pack the best quality by volume. 4 litre packs.
