Pig-iron castings for laying in the heater are made in the form of "grenades" and are cast from high-quality cast iron. They gain more and faster thermal energy than stones, and when water is supplied, they quickly release heat to produce finely dispersed steam. "Grenades" are placed on top of cast-iron bookmarks of the "Bump" and "Pyramid" shapes to increase the mass of the cast-iron mortgage, or mixed with stones for faster and more uniform heating.
