Recently excavated artefacts from Bristol's glass industry are due to be put on show to the public.
The glasshouses had distinctive cone shapes
Archaeologists have spent a month excavating Portwall Lane, opposite St Mary Redcliffe Church where two 18th Century glasshouses were sited.
In their day the cones of the buildings and the towers and spires of Bristol's churches dominated the city skyline.
The archaeological investigations should be completed in June 2006 when the site is due to be redeveloped.
At least 15 glasshouses are known to have been producing bottles, clear table glass and window glass.
The two cones at Portwall Lane were run by the Warren family until their closure in the early 19th Century.
Visitors to the site can view the excavation in progress and see the remains of a glasshouse.
