Exhibition catalogue on the process of transforming raw materials such as iron ore and coal into steel, which, among thousands of other uses, can also become a work of art. The exhibition was designed by the curator Franklin Espath Pedroso, based on three of the most relevant names in Brazilian sculpture, whose works flourished from the second half of the 20th century, in the city of Rio de Janeiro. Presents to the visiting public a selection of 28 sculptures produced in steel by Amilcar de Castro (MG, 19202002), Franz Weissmann (Austria, 19112000) and Waltercio Caldas (RJ, 1946), whose focus is on the poetic use of a material traditionally linked to industrial production.
