The products are made of lava from the Indonesian island Java.
The lava is chopped into blocks so it is easier to work with. Then it is either turned, chiseled or crocheted - depending on which MUUBS product is to be produced.
Finally, the Lava products are treated with a water-based matte top coating, which is approved for food contact.
