Exploring Bristol’s historic glass industry: archaeological investigation at the Soap Boilers’ and Hoopers’ glasshouses, and the Powell & Ricketts’ Bottle Works, Avon Street, Glass Wharf, Bristol

SUMMARY: In 2007, extensive archaeological excavation was undertaken on an important post-medieval glassworking site at Glass Wharf, Bristol. The excavation exposed remains relating to a series of glassworks dating between the early 18th and early 20th centuries and, significantly, uncovered a sequence of five glass-melting furnaces and covering structures, which together reflect wider changes in glassmaking technology throughout these periods. Detailed scientific analysis of glassworking debris from the excavation has also been undertaken, which provides much-needed detail on the development of recipes and raw materials used in bottle manufacture during the 18th and 19th centuries.
