_Glass._—Much broken glass is usually found on Roman sites, vessels, window-panes, etc., and it was probably wrought, in many centres, from imported material. Evidence of this has been found at Silchester and elsewhere (see Mr. T. May’s _Warrington_). Some window glass was described by Price as “plate polished on one side and ground on the other”; this probably means that it was cast and that the rough side came next the mould. Conyers, describing the finds on the side of St. Paul’s in 1675, says: “The labourers told me of some remains that were found up and down near the place of the other pot-kilns, and these had a funnel to convey the smoke, which might serve for glass furnaces. For though not any pots with glass in them whole in the furnaces were there found, yet broken crucibles, or tests for molting of glasses, together with boltered glasses such as are to be seen remaining at glass-houses amongst the broken glass, which were glasses spoilt in the making, were there found, but not plenty, and especially coloured and prepared for jewel-like ornament, but mostly such as for cruets or glasses with a lip to drop withal of a greenish light blue colour. Of any sort of glass there was but little; so that the glasswork might be scarce, for I think a hundred times more of pots was found to one of glass.... “Now doth appear the Romans had excellent mechanics, pot makers, stampers of coins, and excellent workers in glass, for amongst those Roman pots were found glass beads as big as could be put on your little finger, and these hollow within and of blue glass wrought or enamelled with yellow glass, and blue beads of the colour of a Turkoise stone. Divided were these beads with threads as big as pack thread. Amongst the rest, great pins made of bone or ivory, etc., heads of many like the great brass-pins, and others vermicular or screw-head, others like the Pope’s triple crown; of these fell to my share as many as a pint-pot would hold.... Taken up a _speculum_ of metal to show the face, of fine bell-metal. There were also found brass embossments with glass set instead of better jewels, which I keep, and glass drops that were loose, and the bottom of an old-fashioned crucible which had glass melted in it, and there were also pieces of necks of glass cruets to pour out by.” Much of the large number of plainer glass vessels in our museums was doubtless made in the London glass works from imported metal, and probably some ornamental pieces were also manufactured. Thomas Wright thought that glass itself was made in Roman days on the coast near Brighton where “pebbles of glass” have been found; but from comparatively late records of glass making about Rye, etc., the Roman origin of the “pebbles” seems unlikely.
