Stone is one of the most common blocks found naturally in Minetest Game. It can be found at any height level down from the surface level except in deserts and the entire underground is mainly made out of stone. Mining it gives cobblestone which can be smelted into stone again. To mine it, you need a wooden pickaxe (or better). Stone is also important in the sense that all ore blocks spawn inside stone.
Stone is created when flowing lava is touched by a lava-cooling block (even diagonally or at a corner): water, river water, ice, snow block. As long the lava source is not destroyed in the process, it is possible to create an unlimited amount of stone that way.
