What is Grupo Ruptura?
Grupo Ruptura was an organization formed in Brazil by artists who sought to break away from traditional naturalist painting in favor of geometric abstract art. In the early 1950s, the group published the Ruptura Manifesto, advocating for new art for a new country. The manifesto emphasized a departure from the past and a commitment to innovation, aligning with the modernist vision of Brazil as a forward-looking nation.

Offset lithography is a printing technique where the inked image is first transferred (offset) from a plate to a rubber blanket and then to the printing surface. This method combines the lithographic process, which relies on the repulsion of water and oil, to keep non-printing areas ink-free by attracting a water-based film. Offset lithography was originally developed to reduce costs in reproducing artwork and is widely used for high-volume printing due to its efficiency and ability to produce sharp, consistent images.
Engraving is a printmaking technique where a metal plate or surface is directly cut using a sharp engraving tool called a burin. The tool creates deep lines or grooves, which are then filled with ink. The plate is pressed onto paper with heavy pressure, transferring the inked image. This process results in a clear and precise print.
Metal has been traditionally used in art for creating sculptures, jewelry, masks, adornments, tools, and weapons, often featuring decorative elements. Common types of metal used include bronze, brass, cast iron, gray iron, copper, gold, tin, wrought iron, and silver.
