Advice needed. Having completed approximately 75% of a glass piece chipping, the humidity and heat were interrupted for 10 hours. Which is the preferred method to resume chipping? Simply resume the process or remove glue and apply new glue to unchipped area with proper heat and humidity. This is a matter of utilizing time and labor. Your observations are welcomed. Bob

I'd just put it out in the sun. It should all chip off. However, having the rest chip in a different environment could cause the chip pattern to be different. Perhaps first try resuming the process that was interupted.

Agreed.

Robert,
Please come back to the post and let us know how the glass is doing.

We may have additional suggestions if your piece still won't finish chipping.

Hello. As advised, I simply continued the process with the original glue in place. Worked fine. My concern has been expressed by so many when we live in an area that has relatively high humidity. Seldom below 50 per cent. For smaller pieces, such as the current one, I use a tent affair (Box) over a room humidifier. It appears that the humidity is controlled and the unit produces heat which helps the process. Appreciate the kind advice. Thanks again. Bob

Hi Robert.
Back when I was experimenting with chipped glass I used to place the glass with the glue already dried into a double glazed sealed unit with desicant spread around the edges.
Basically two pieces of glass sealed with an inch trim 4ft by 5ft air tight it used to work very well.I also have high humidity here next to the coast,it can be a pain. Get yourself that lightbox I was talking about you won'nt get any further problems.
