Shortage of raw glass forces recycling in Roman Britain

Glass was a common commodity in Roman Britain until the 3rd and 4th centuries C.E. when a shortage of raw glass forced recycling. A new study of Roman clear glass appears in the Journal of Archaeological Science.

Skilled Roman glass craftsmen were able to use a decolorizer to remove mineral coloration from glass, but analysis of recycled clear glass showed color-causing minerals contained in the glass.
