The distinctive green tint in the window sashes of @tcddublin’s Examination Hall is caused by a concentration of iron oxide in the sand used to make its 1780s crown glass. The pinkish hue is the result of manganese used to counter the green tint. Magical survivors

Handblown glass is one of the most precious resources of old buildings and historic streetscapes, lending life, character and a vivid connection to the skilled tradespeople that built them. It is protected under Protected Structure and Architectural Conservation Area designations

There are a variety of solutions for thermally upgrading old windows without disturbing their special character including draught-stripping, secondary glazing and demountable sheet glazing – remembering that the individual requirements of an old window should always be considered
