Natural volcanic lava rocks for use with gas barbecues. 4kg box Lava rock retains & reflects heat in a barbecue, absorbs excess grease & helps create that smokey barbecue taste by evaporating the juices that drip down from the meat. Lava rock helps your gas barbecue to heat up sooner, retain heat & consequently radiate heat for better cooking. Please note
- Lava rock is not required if your barbecue has the flavorising bars function. The quarrying of lava rock is licensed by the Icelandic government to ensure it is not detrimental to the local environment & only takes places where there is no surface vegetation.
