Fortunately we had enough in our Building Fabric Fund to cover the cost of the restoration and the work has been completed and the window is back in place.

Here's what Clifford G. Durant &Son, the Stained Glass Artists said about the window : South facing single light lancet, cusp head in stained and painted cast glass quarries. 

HISTORY OF CAST QUARRIES.

Nineteenth & Twentieth cast quarries which sometimes are referred to as pressed or stamped quarry decoration, were once quite common but today they are quite rare. Produced & patented by the London Company of James Powell & Sons from their site near the River Thames (latterly known as Whitefriars in 1923 when they moved to Wealdstone) These quarries were produced by pouring molten glass into pattern moulds producing very many different designs, once annealed and cooled the individual pieces would be painted and latterly stained within the indented pattern and fired in to result in a semi obscured glass decorated with either black or brown pigment and yellow stain from light yellow to amber stain. We must bear in mind that this glass is over 150 years old, the base glass has not been manufactured for decades.
