Glass Male Urinal This is a glass male urinal. It features an elongated, cylindrical body with a flattened base, ensuring stable horizontal placement. The proximal end has a wide, flared inlet to facilitate use. The surface is smooth, without any embossing, but contains small air bubbles from the glass-making process. These bubbles, known as gas inclusions, occur naturally during the melting and forming stages when air or gases from the raw materials get trapped in the molten glass. This type of urinal was commonly utilised in healthcare environments throughout the early to mid-20th century before being superseded by lightweight, disposable plastic alternatives. 1900-1949
