In the late 1760s, the arms factory in Zlatoust was sold to Larion Ivanovich Luginin, a Tula-based 1st-guild merchant; in 1797, his grandson leased it to another 1st-guild merchant, Andrey Andreyevich Knauf. In 1799, the factory was sold for 1.8 million rubles in government banknotes to a bank and entered into the jurisdiction of the Mining Collegium.
In 1800, along with other factories of the Zlatoust Mining District (Satka, Kusa, Miass, Arti), it was again leased to Knauf under “special arrangements that could not be made public.” In 1811, the plant was finally taken into state ownership.
At the turn of the 19th century, 20 blooming hearths and 20 hammers operated at the Zlatoust Arms Factory, up to 210 thousand poods [1 pood ≈ 16 kg] of cast iron were smelted, various grades of iron were produced: band iron (up to 70 thousand poods per year), profiled iron (up to 50 thousand poods), flattened iron (up to 40 thousand pounds), plank or sheet iron (up to 10 thousand poods).
Three cylinder-shaped gun barrels with the stamp “Z.O.F.” on a black-painted wooden stand, were made of Zlatoust steel in the second half of the 19th century. They were exhibited at the Moscow All-Russian Industrial and Art Exhibition of 1882. For the manufacture of gun barrels from open-hearth steel, the factories of the Zlatoust Mining District were awarded a silver medal.
The expert commission of the industrial and art exhibition recognized the mining plants of the Zlatoust State Mining District as worthy of a diploma of the 2nd category for the methods of using open-hearth steel for the manufacture of gun barrels, for the introduction of metal baths for hardening blades, for the introduction of emery grinders, as well as for experiments that reduced the cost of manufacture of steel products.
The barrels of the first Berdan rifles — single-shot rifles, which were named after the American Colonel Hiram Berdan — were made at the Zlatoust plant and supplied for weapon assembly in Tula. In 1960, these gun barrels were transferred to the Zlatoust museum from the museum of the Plekhanov Leningrad Mining Institute (known as the Mining Institute until 1917).
