the furnace, while the hand bellows were activated by human forces, as it was in the bloomery
furnaces. Hand bellows could not drive air through a 3 - 4 meter layer of raw materials.
This difficulty was overcome when metallurgists called on the power of water to help them,
when the blowers belts were driven by mill wheels. The wonderful art of Russian "water people",
builders of hydraulic power plants, and craftsmen who created powerful bellows, helped to build
the world's tallest blast furnaces on the banks of the Tulitsa River at the beginning of the 17th
century.
A few years after the founding of a metallurgical plant in Tula, nearby, in Porotov, another
similar plant was built. Then the Kashirsky iron foundries appeared in the neighborhood.
So in the Tula region, in a short time, a large mining center, equipped with excellent technology,
grew up. This was a major success for Russian metallurgy. It was soon followed by other
successes that were already of global importance.
