Patina is the distinctive greenish surface that bronze develops over time due to exposure to air and humidity. Artists can also apply chemicals to bronze to artificially create patina. Alternatively, bronze can be polished to reveal its natural rich gold color. Patina is not exclusive to bronze; it can also occur on other metals like copper and even on wood and stone, enhancing the material's character over time.

Postminimalism refers to a range of art styles that emerged in the 1960s, following the Minimalism movement.
