“ Priming is a thin coat of paint with a small amount of red lead in it. In the majority of cases after the sashes for the windows are fitted they are sent to the glazier’s and primed and glazed, and then returned to the job and hung in their proper positions. When priming sashes it is important that the rebates be thoroughly primed, else the putty will not adhere. All wood that is to be painted requires before being primed to have the knots coated with knotting. ”

“ Care should be taken not to fit the glass in iron bars tightly, but a good 1/8th in. play all round should be allowed. A few of the systems of patent roof glazing will be described in the following pages, together with illustrations.
The system of glazing known as the “British Challenge” (fig. 3) , with steel bars encased with a sheeting of 4-℔ lead, is very simple and durable, needs no painting, and can be fixed at as much as 8 ft. clear bearings, with the bars spaced 2 ft. ”

“ This is rarely an easy matter, especially in towns where the aspect of the building is out of the architect’s hands. The best sites for light are found in streets running north and south and east and west, and lighting areas or courts in buildings should always if possible be arranged on these lines. ”

“ Glaziers’ materials are glass, putty, priming or paint, springs, wash-leather or india-rubber for door panels, size, black. The glass is supplied by the manufacturer and cut to the sizes required for the particular work to be executed. Putty is made of whiting and linseed oil, and is generally bought in iron kegs of 1/2 or 1 cwt.; the putty should always be kept covered over, and when found to be getting hard in the keg a little oil should be put on it to keep it moist. ”

“ The task of adequately lighting lofty city buildings has been greatly minimized by the introduction of many forms of reflecting and intensifying contrivances, which are used to deflect light into those apartments into which daylight does not directly penetrate, and which would otherwise require the use of artificial light to render them of any use ”

“ An invention has been patented for building houses entirely of glass; the walls are constructed of blocks or bricks Use in building. of opaque glass, the several walls being varied in thickness according to the constructional requirements. ”
