This is a big piece of art. 
An artist named Marcel Duchamp made a big art piece. 
Marcel Duchamp made a very large artwork. It is called The Large Glass. 

Marcel Duchamp created a massive artwork called *The Bride Stripped Bare by Her Bachelors, Even*. Many people also know it as *The Large Glass*. It is over six feet wide and very tall. 
Duchamp used many unusual ways to make his art. He used lead wire to outline shapes on the glass. He also used oil paint in colors like gold and brown. 
The artist worked on this piece in New York City. He started his ideas in 1912 and worked from 1915 to 1923. 
The glass has two main sections with different looks. The top is the Bride's Domain, which uses cool colors like beige. 
An accident changed how the art looks today. In 1926, the glass broke while it was being moved. 
*The Bride Stripped Bare by Her Bachelors, Even* is a massive, complex artwork by Marcel Duchamp. It is also frequently called *The Large Glass*. The piece is over six feet wide and very tall. It consists of two vertical glass panes. Duchamp worked on this project in New York City from 1915 to 1923. The work is famous because it blends meticulous craftsmanship with chance procedures. It is not just a visual object. It is a conceptual machine that uses a unique set of rules. 
Duchamp used several unconventional methods to create the piece. He used lead foil and fuse wire to outline shapes. He filled these shapes with oil paint in earth tones like gold and brown. To create certain shapes, he used the wind. He hung gauze in a window and photographed it. He then reproduced those wind-blown shapes on the glass. He even used a toy cannon to fire wet matches at the glass. This placed shapes called "shots" using chance rather than his own hand. He even used real dust from his studio as a pigment. He glued the dust down with varnish to capture the passage of time.
The artwork is divided into two distinct sections. The top rectangle is known as the Bride's Domain. This area is almost entirely monochrome. It uses cool colors like beige to resemble a cloudy sky. The Bride herself appears as an insect-like group of geometric forms. She is connected to a cloudy "halo" at the top. The bottom section is called the Bachelors' Apparatus, or *La Machine Célibataire*. This area uses warmer colors like dark brown and gold. It features a large mechanical assemblage of shapes. 
Inside the Bachelors' Domain, several specific parts exist. There are nine shapes called Malic Molds. These dark brown shapes resemble empty clothes hanging on a line. They are tied together by a spider web of thin lines. They connect to seven conical cylinders. These cylinders change from transparent to opaque in a rainbow-like line. A central pole connects these cylinders to a chocolate grinder. This grinder has three textured, drum-like structures. Other parts include X-shaped rods and a machine that looks like a waterwheel. 
Duchamp's history with the piece is marked by long periods of inactivity. He began his initial studies and notes in 1912. He admitted he was often "lazy" and worked only two hours a day. He did not originally intend to sell or show the work. Because he worked sporadically, the glass sat untouched for months. This allowed thick layers of dust to settle on the surface. In 1926, the piece broke during transport to the Brooklyn Museum. Duchamp chose to glue the pieces back together rather than replace the glass. He felt the resulting spider web cracks added a necessary element of chance.
The significance of the work is tied to its accompanying notes. These notes were published in 1934 as *The Green Box*. Duchamp intended for the book to accompany the glass. He wanted to prevent viewers from having a purely visual response. The notes describe a "hilarious picture" of an erotic encounter. They explain the physics and myths of the machine. Some critics see the work as a study of male and female desire. Others view it as a "machine of suffering" where the two realms are separated forever. 
Today, the original work is part of the Philadelphia Museum of Art. Duchamp also sanctioned several replicas of the piece. One was made in 1961 for a museum in Stockholm. Another was made in 1966 for the Tate Gallery in London. A third replica is located at the Komaba Museum in Tokyo. The work relates to many different fields of study. Mathematicians and philosophers have read complex systems into its structures. It remains a primary example of how chance and intention can meet in art.
