GLASS RECIPES AND THE OUTPUT FROM A 19TH-CENTURY GLASS WORKS: EXAMPLES FROM PERCIVAL,VICKERS & CO. LTD,MANCHESTER

Abstract

Excavations by Oxford Archaeology North in 2003 revealed extensive structural remains of the former Percival, Vickers and Co. Ltd glass works, one of the principal 19th-century glass manufactories in Manchester. A detailed account of the excavated remains, focusing on the significant developments in furnace design inherent in the exposed structures, has already been published in volume 29.1 (2007) of the Review. However, an in-depth analysis of the 187kg of glass fragments recovered from the excavation was omitted, and this shortcoming is addressed in the present paper. Scientific analysis of the glass compositions revealed that a variety of recipes were used, and these related closely to the different ways that glass was being worked on site, as evidenced by the various types of waste. A relatively small but nevertheless significant number of vessel fragments were also recovered, allowing the output of the glass works to be characterised for the first time.
