Bristol Blue Glass is a rich cobalt-blue glass traditionally produced in Bristol, England, from the late eighteenth century onwards. Renowned for its deep, vibrant colour achieved by adding cobalt oxide during manufacture, Bristol Blue Glass has been used to create bottles, decanters, vases, scent bottles, tableware and decorative ornaments. Antique examples are highly prized for their colour, craftsmanship and association with one of Britain\'s most celebrated glassmaking traditions.
