Glue Chipping Light Box (glue chip)

OLD FORUM POSTS

I was hoping Dave Smith would share this method of glue chipping, but in talking with him recently he'd asked to post this on the board. He got the idea from reading Bob Mitchell's book on glue chipping glass.

Dave took an old sign can with fluorescent tubes in it, approximately 3 x 10', and had it modified with bulbs spaced every 4 inches. An acrylic cover was inserted on the face, and the normal electrical holes were left open for ventilation.

The glass was prepared and glue applied allowing it to dry naturally without a fan.

The light box was put against the wall at an angle, and the glass placed against the acrylic. At 9 the next morning he turned the light box on and placed the glass against the box. By 4 in the afternoon the glass was chipped with a nice fern pattern. The temperature on the surface of the glass never exceeded 70 degrees and the humidity was in the range of 35 - 40%. The glue / water ratio and glue were the same as Rick used.

A second box is being made that will give him a 6 x 10' box, and his original cabinet is being dismantled.

I've tried this on a several small pieces with similar results.

Thanks Danny
The humidity actually got down to 25% and tempature around 80. like Danny said I managed to get a very fine chip and it works evey time.
works as-well when it's raining.

Is the glass to be chipped inside the box, or resting against it on the outside? Couldn't quite tell...

Catherine.
The glass is on the outside of the box.
The lightbox I had made is 3' in height 10'in length and 6'' depth. As Danny said the bulbs
are spread about 4'' apart and slightly stagered
to take up room. On the face is one sheet of glass
either touchened glass or laminated 6mm thick. Then on top of the glass is opal white 3mm perspex the whole area keeps the humidity and temprature the same all over. The opal perspex is only there for light to pass through so I can use it for general graphics etc..

Dave.
