Use a heat gun or a hair dryer on its highest setting to soften the old putty, being careful not to scorch the wood. Once pliable, scrape it away with a stiff putty knife, working at a low angle to avoid gouging the frame. After the bulk of the putty is gone, you will see the glazing points. Remove these with a pair of pliers or a flat-head screwdriver. Finally, use a solvent like denatured alcohol or a commercial paint remover to clean the wood down to its bare surface.

Once the large pieces are gone, lay a drop cloth or old newspaper on the floor below the window to catch any falling debris. Take a moment to measure the opening precisely: measure the height and width of the rabbet (the inner ledge of the frame) in three places each, using the smallest measurement to ensure a proper fit. Then, subtract 1/8 inch from both dimensions to allow a slight expansion gap for the new glass. Have this glass cut to size at a local hardware store.
