An old chisel can be used to clean off old putty before setting glass. On new work, see that the rabbet or shoulder where the putty is to go is primed with lead paint before putting on the putty (see Painting). You can buy glazier's points, to hold the glass in position under the putty, for a trifle, or very small brads can be used. No special directions are necessary for using the putty.

To set common glass in furniture, as in bookcase doors, it is better to fasten it in place with small strips, not pressed too tightly against it. Strips of plain moulding are good. To set plate glass in furniture, the same means can be used for small pieces, but large plates, as for a mirror, should be held in place by little strips of soft pine, one or two inches long, bevelled on one side. The other side being glued, these strips can be lightly pressed into the crack around the glass. These short pieces, glued to the frame on one side and with the bevelled side wedging the glass into place, hold the latter securely, but, owing to the softness of the wood, not too rigidly.
