Physical description

The main component of the nitrous oxide gasometer is a reflective white metal urn-shaped chamber from which an outlet valve and circular moulded tap allows for the flow of gas. A rectangular frame sits atop the chamber and comprises ornately decorated metal flourishes and three white metal anchoring pipes, two attached to each side of the chamber and one attached to the centre of the two-tiered, domed lid. The gasometer sits atop a Y-shaped cast iron stand, ornately decorated with metallic golden brass paint, with a circular base. There is also a black cast iron ring that is attached to the stand. Manufactured by Buffalo Dental Manufacturing Company, Buffalo NY.
