Belgo-Mineira Steel mill. João Monlevade (MG), 1941(?)
“1.300º in the shade of sheds
12,000 invisible horses thinking
40,000 tons of yellow nickel
To overcome the spongy waters
And a railway sprouting from the ground
From the mighty furnaces
Come pig iron and slag
The refining plants bars
And down there workers
Forge the first slivers of steel”
Oswald de Andrade, Metalúrgica, Pau Brasil, 1925
Oil rig. Bacia de Campos (RJ).
