Stoneheated

Stoneheated is a term used to describe a heating method in which heated stones serve as the primary heat source or as a heat reservoir. In practice, stones are heated in a fire or furnace and then placed in contact with a space, vessel, or object to radiate heat. The concept appears in traditional cooking, saunas, and various forms of passive heating that rely on stone masses to store heat.

Mechanism and materials: The performance depends on the stone’s thermal mass, heat capacity, and durability. Stones chosen for culinary use are typically non-porous and food-safe; for architectural or spa uses, durability and resistance to cracking are prioritized. The heat is released gradually, providing sustained warmth after the initial heating phase.

Applications: In cooking, stone ovens and hearths use hot stones to bake and roast. In saunas and baths, heated stones radiate warmth for extended periods. In some rural or artisanal settings, stone masses function as simple heat storage for spaces or equipment.

Safety: Handling heated stones requires care to avoid burns, and improper selection can lead to cracking or contamination.
