BRONZE: it is one of the oldest known metals, its composition is copper and tin, two soft metals that when melted acquire properties of extraordinary hardness and strength.
SAND FOUNDRY: Cast iron system that Pedro de Andrés often uses, sand molds are created that are used only once, which is why they are very laborious and artisan processes.
REVIEW: After the casting comes the revision phase, it consists of removing the edges and marks left by the molds, finally polishing.
PATINADO: The dark bronze that we usually see in exhibitions does not appear that way naturally, it is a process that is called "patina". Each artist gives a termination according to his criteria, in the case of Pedro de Andrés, he uses a procedure that we will not discover to be a professional secret.
I'll just say that, the finish we see is done through a rapid oxidation process, combination of temperature, acids and time. The figure is heated, reached the point of temperature, is immersed in acids for a while, which causes the oxidation of bronze, having a high copper content, the oxidation gets these iridescent between blue and green.
FINAL FINISH: The figure is polished again and mounted on a marble base.
Sculpture style: Impressionist figurative.
