Name/Title
Brass PortholeEntry/Object ID
2022.2.104.16Description
This two-dog round brass porthole was once part of a lake freighter. Portholes were used in the hull of ships to admit light and air.
Most portholes are made from strong materials such as brass, iron, or steel and are made in round, oval, or square shapes. Round portholes provide greater structural integrity against wind and water. Other shapes tend to be more susceptible to stress. In addition, portholes are produced with two to four "dog ears," also known as "keys," that secure the window.
Bulk carrier vessels were also referred to as 'lake freighters' or 'lakers' carrying bulk materials (i.e., grain, salt, coal, sand, limestone, etc.) through the Great Lakes of North America.Location
