ANALYSIS OF POST-MEDIEVAL GLASS AND GLASSWORKING DEBRIS FROM OLD BROAD STREET, CITY OF LONDON
Author(s): C Mortimer
Crucibles, glass waste, vessel fragments and opaque-white canes were examined and analysed chemically. Most of the material was soda glass, but three potash glass beaker fragments and four high-lime, low-alkali glasses were also analysed (one beaker and three bottles). Six coloured glasses were also soda glass based, but two pieces with very unusual colours, one very dark brown and the other opalescent, were made of high-lime, low-alkali glass. A dark blue trail in a vetro a fili fragment was coloured by a cobalt oxide; arsenic and nickel oxides were also detected. All the material is from contexts dating from the first half of the seventeenth century, and may relate to a workshop clearout from Robert Mansell's glassworking premises.
