John Moncrieff was born in Cherrybank, Perth in 1834. He began working with glass in 1847, when he took a position at Perth Inc Works. He started his own company in 1868, initially naming it the North British Glass and Ink Works, and later renaming it John Moncrieff Ltd. “The superior quality of Moncreiff’s products earned the company an international reputation and its gauge glasses, marketed under the brand names ‘Perth’ and ‘Unific’ were sought world-wide by locomotive companies, steamship companies and the British and foreign Navies.” (ref.2) (From Artifact Worksheet) - Function
-
To indicate water levels inside of boiler. - Technical
-
The level of water in a steam boiler must be carefully controlled to ensure the production of quality steam in a safe and efficient manner. This steam is generated by heat from the combustion of fuel in a furnace. As steam is generated, the water in the boiler evaporates and the boiler must receive a supply of water to maintain level, pressure, and efficiency. To monitor this level, a gauge glass on the boiler shell is used as the indicator. The glass itself is designed to withstand heavy pressure and breakage. (From Artifact Worksheet) - Area Notes
