A glass cone is a glass production structure historically unique to the United Kingdom. A glass cone had a large central furnace, a circular platform where the glassblowers worked, and smaller furnaces around its wall to ensure the glass did not cool too quickly.
There are five surviving glass cones: Catcliffe Glass Cone, South Yorkshire Lemington Glass Works, Newcastle upon Tyne Northern Glass Cone, Alloa Glass Works, a Scottish scheduled monument, Red House Cone in Wordsley, granted listed building status in 1966 Pilkington's Jubilee Cone, St Helen's, restored in the 1990s and now the entrance to the World of Glass
