Glass and other vitreous materials

Recent analytical results and their interpretation, particularly in the fields of coloured and lead glasses, are reviewed. Much attention has been given to production dynamics ‐ furnace temperatures and atmospheres, and times of formation ‐ in an attempt to explain products which cannot be interpreted from their composition alone. Current work on freshly excavated material of this kind from a number of sites in England is described. There are intriguing possibilities in the study of lead glasses, especially sealing‐wax red, in relation to origins and movement.
