14th December - Bristol Red and Bristol Blue

Everyone knows of Bristol Blue cobalt glass, but few have heard of William Cookworthy's involvement with it, and his three important discoveries. Few too have heard of Bristol Red. It depended crucially on Alum. An Elizabethan naturalist discovered the secret of making alum from shale, and broke a lucrative Papal monopoly during The Reformation. This was the start of an industry based on rocks dug from the North Yorkshire coast, the Thames Estuary, and at Campsie, near Glasgow. Alum was made in Bristol for over a hundred years, until the 1970s.
Everyone is welcome - mince pies and refreshments - courtesy of WEGA.
