These steels then normally consist of y-iron, modified by the large amount of nickel or manganese with which it is alloyed.
of zinc, all the gold and copper and some silver and lead will be alloyed with the zinc to a so-called gold - or copper - crust, and the residual lead saturated with zinc.

A sheet iron case is then placed within the furnace, and the space between it and the walls rammed with limed charcoal; the interior is filled with fragments of the iron or copper to be alloyed, mixed with alumina and coarse charcoal, broken pieces of carbon being placed in position to connect the electrodes.
