Here's a kinda cool part:In 1773 the factory was invaded by a rebel army of a famous Bandido,Pugachev!
A real to goodness Slave Rebellion.....
The factory serfs were all in favor of joining the mutineers.
250 of them,taking with them 6 cannon,250 muskets,25 swords,600 spears,and 5 pood(almost 200 lbs,not bad
)powder(the factory horses and oxen too),left with the rebel army.
The factory became a fort,and a base for an attack on the city of Chelyabinsk.
In the spring of 1774 Pugachev hisself entered the factory at the head of his main army,and the rest of the factory hands left with him as he carried further on...
The factory was sacked,water from the dam drained,the water wheels chopped up,and the entire mess,including the administrative complex and the owner's quarters burned.
It took a few years to restructure the Works.In February of 1776 the blast furnaces started again.
Many buildings were replaced by brick.
The enrichment of ore was now done right at the Works themselves.
Puddling baths/furnaces were built,that were fired by a complex system of flues,unique to the region.
Now,in 24 hours, the yield was 550 pood of cast ("pig")iron of two sorts:White,that was to be refined into iron,and Grey,used directly for cast products.
In converting,15 p. of White cast iron made 10 p. of wrought iron,or losses of 33%.
Ok,i think that's about all there is of much interest....
