[1] It was used by the Stuart Crystal firm till 1936,[2] when the company moved to a new facility at Vine Street.

[6] A 1-acre (4,000 m2) site, on which the cone stands, was sold by John and Ann Southwell and Rebecca Stokes to Richard Bradley, a wealthy glass-manufacturer, on 21 June 1788.

The cone was built by Bradley in partnership with his brother-in-law, George Ensell, for the manufacture of window glass.

[7] Ensell installed a moving lehr in the cone, which remains today and is the only surviving one in the world.

[8][9] In April 2022, the Cone received a pledge of £1.5m from Dudley Council in order to restore the structure.
