I am about to replace some panes in the windows of an old building (WWII!). They have metal frames each pane is about 9" square. I have 2 questions.
i) Is there a modern material to replace linseed oil putty? The latter is a messy substances to work with.
ii) Assuming I could cut glass to the necessary accuracy [:-(], what clearance should be left between pane and frame?
TIA Frank
