Exterior of Ballindalloch Church, Morayshire, showing four of nine zinc framed windows, all of which required full on-site conservation.

Rose window

The main cause of deterioration was exposure to wind, rain and condensation over 100 years. The wooden frames were rotting. The zinc frames and iron bars were corroding, and the glass had layers of mould and cobwebs on the surface.

Interior lancet

Overall, each lancet, although very simple, created a lovely tartan pattern throughout the church. A beautiful use of coloured antique cathedral glass.

Lancet interior

Where necessary, the glass was carefully removed from the frames, piece by piece.

Removing the glass

Many of the individual pieces of glass were broken and had to be removed from the frame.

Broken glass

Not all of the glass had to be removed. Sometimes inappropriate previous restoration glass was removed to replace with a more sympathetic match.

Glass removed

New glass was carefully puttied into the frames.

New glass

The original glass was carefully laid aside for re-use after the frame had been restored.

Old glass

The zinc frames were tied together using galvanised zinc / steel wire, and tied to painted steel bars. At no time was any copper product used as it would have set up an electrolytic reaction and corroded the frames.

Repairing the frame

All of the old putty was carefully removed if it was loose, and new putty was knived into place. Three layers of oil paint were then painted over the frames.

Finishing off

Cleaning the glass of the fungus, mould and cobwebs was time consuming, and at times a tight squeeze.

Cleaning the glass

Thanks to Maurice Jackson and Norma Hunter who so ably assisted us.
