#industrialheritage #historyofdesign #primaryforms I got to go in the Catcliffe Cone today. This is their first open day - apparently it's the oldest #glass kiln in Europe to still be standing. Many rumours surround it, none can be substantiated. Were prisoners of war once kept here? Was the #stone at the base from the same quarry that supplied Westminster Palace? Why can nobody find any of the glass that was made here?
