Black Vulcanite Sauna Heater Stones, characterized by their fine granular texture and dark grey hue, turn a striking black when wet, making them an aesthetically appealing choice for specific Harvia heaters. These stones, with volcanic roots tracing back approximately 2 billion years, are an excellent selection for sauna stones due to their hardness and durability.

Key Features:

  • Aesthetic Appeal: The stones’ transformation to a shiny black when wet adds a visually appealing element, especially in combination with selected Harvia heaters.
  • Ancient Volcanic Origin: With a history of around 2000 million years, these stones carry a unique geological heritage.
  • Hard and Durable: Vulcanite’s composition and structure make it exceptionally resilient, and ideal for the high-heat sauna environment.
  • Uniform Granular Texture: Their small, consistent granule size ensures even heat distribution.
  • Compatibility with Harvia Heaters: Specifically chosen to complement a range of Harvia sauna heaters.
  • Long-Lasting: Due to their hardness, these stones are less prone to wear and breakage, offering longevity in sauna use.
