Exploded type jagged stones create erratic heat waves. Whereas rounded stones, heat and steam flows around the contour of the stone allowing the heat and steam output to be less erratic. The heat around rounded stones flows out in a smooth stream, and heat is contained and released more evenly. All that means...you get a smoother even steam 'Löyly' and heat flow from your sauna stove. If you have a large sauna this can dramatically improve the quality of your sauna steam.
