I forgot to cover the glazing earlier, but it’s not very remarkable; the glass is held in with cabinetmaker’s glazing compound rather than glazier’s putty. Glazier’s putty is made from whiting and raw linseed oil which makes it very slow drying and the smell of the oil hangs around for an equally long time – which may or may not be an issue depending on your disposition to the smell of the stuff.
Cabinetmakers and clock-makers traditionally used an entirely different formulation to glaze bookcase doors and clock hood doors etc. It was essential that the compound be quick drying so the piece could be handled virtually straight away. Whiting still forms the basis of the compound, but strong shellac (normally a four-pound cut) is the binder. It must be mixed very stiffly; otherwise the compound will flow until it sets – which actually doesn’t take very long.
I pressed the compound in and around the glazing bars with a stick and smoothed it with a wetted piece of stout leather. A final lick of ‘murky’ shellac further ages it all.
