DIRECTIONS FOR PREPARATION AND USE OF GLASS CHIPPING GLUE
- You will need:
Etched or sandblasted glass to be chipped. The class should be thoroughly clean and grease-free
- Clean glue pot, or double boiler
- Stirring stick
- Thermometer
- Masking tape
- Level working surface
- Drying area held at about 100 degrees F.
Measure the glass surface to be chipped and determine the area in square feet. You will need about ½ c. of glue solution for each square foot of glass. The glass should be about room temperature, or slightly warmer, to permit the glue to spread as needed before it gels.
With masking or similar type tape, (and being careful not to get any grease or dirt on the glass), frame the area to be chipped. The tape will contain the glue in the area to be chipped.
In a clean, electric glue pot or double boiler, add 1 part glue to 2 parts water. Stir a little and allow the mixture to soak for about an hour.
Heat the mixture, stirring occasionally until it reaches 140 degrees F. (If the glue is too hot, it may crack the glass as it is poured.)
Pour the liquid glue onto the glass and tilt as necessary to distribute the glue to the taped boundaries. The film of glue now should be about 1/16 inch thick.
Allow the glass to rest and cool on a level surface for a few hours, or until a fingernail pressed into the edge of the glue makes a slight dent. Now, the chipping may be accelerated by placing the glass in a warm, but not hot (100 degrees F), drying area until it has finished chipping.
CAUTION: glue chips contain very sharp glass! Do not remove them with bare hands. A clean paint brush works well.
