I work for Russell Kelly in Toronto and we are having a little problem with our glue chipping. We are doing everything the way we always have but we are getting very little chip. The glue is mixed 1.5oz glue to 3.75 water, swelled, heated to 150F and poured hot. This recipe has worked for years here and in the last 6 to 8 months the chip has been getting worse(less). The only thing that has changed is our location of chipping. We just chip in another room. Does anyone have any suggestions to help get a better chip?

Build a plywood box to get rid of the moisture, build a box out of some dry raw plywood or even a cardboard.
I'd have to say that with the info you've provided, it's the room change, was it in a room with a wood stove, Did the other room have a wood stove or was the table closer to the heater?
Something most likely is keeping the humidity levels high.
How old is your glue, or has it been contaminated?
Is the glass from the same supplier?
Are you blasting the areas to be chipped well enough, providing enough tooth to assist glue.
Rick Glawson suggests a water to glue mixing ratio of 1 part glue to 1 1/2 parts water.
Check out Bruce Jacksons site, it may assist you.
Good luck

I think Ron and Coop are on the right track. Glue won't chip worth a hoot if the humitity is more than about 40%. A box with a couple of 100w light bulbs is usually enought to bring down the humidity.

Thanks guys.. All the glass is from the same place. I will get a de-humidifier as well as some heat in here. I am going to do a bunch of test pieces before we try this on our next bar mirror next week.
It is going to be tricky to enclose some of the bigger glass pieces (4'x8'), but I guess we can just "tent" them in temporarily.
