This will stop them from breaking due to heat. After you have removed the old glass, take a damp cloth and clean the inside of the window sash to get rid of any dirt or dust.

After the frame has been cleaned and ready and ready to be used, warm a few tablespoons of putty by kneading until it's soft and malleable. Utilize the putty knife to apply a thin layer to the inside corners of the rabbets, forming an elongated bed for the glass to rest on. Repeat the process for the remaining exposed edges.
