To stop stress cracks from occurring make an arc using glass cutters near the crack. This stops the crack from spreading, and may slow it down by a day or so.

Measure the frame of the damaged window to determine the size of the new pane. It should be slightly bigger than the opening to allow for expansion and contraction and also to compensate for any imperfections in the frame or on the glass. After you've cut your glass to the proper size apply glaziers' compound around the edges of both the frame and the glass. After the compound has dried paint it in a manner that matches the frame.

The spacer is made up of desiccant which is highly absorbent and will absorb any excess moisture.

This can lead to moisture leaking into the gap once the desiccant has been saturated. This can lead to condensation and water in the gap and is very difficult to get rid of.

Apply a coat linseed to the rabbet and wipe it down. This will help the putty to stick.

After the frame has been cleaned and the rabbet is prepared, it's the time to plan the replacement of the broken pane. Find the height and width of the opening both ways Then, you can order an item of double-strength glass that is 1/8 inch shorter in both directions. Also, you'll need to purchase glass points, which are made of metal triangles which help to hold the glass in the right place.
