Robare M. NovouNow where did I store my dunce cap?
well number three was all but a charmer, I came into the shop today and the 3rd test was starting to chip, It chipped about 90% when it stopped for about 2 hours, so in an attempt to help it along I applied a heat lamp. it broke!
the humidity was higher today, I did get more of the glass to chip but I still had a lot of frosted areas. The glue was at least 1/16th of an inch if not a bit thicker. Maybe I'll take a break........no punn intended. lol
How thick is your glass?
Rob Rochon
Robare M. NovouIts standard plate glass 1/16" I beleive, these are just test peices the size is 8x10
I
Larry White - Could it be the glue?would think that your glass may be to thin.
I used to use thin Single and Double Strength Window glass. and I had some problems with breakage.
I now use 1/4 or 3/8, no more breakage...unless I drop it. Even if you're testing some technique...you break your glass chipping it and never get to the next level.

Mike Jackson - Glue info and sourceI remember a conversation I had with Rick Glawson in which he went on (..and on) about how the manufacturer of the glue had changed some of there process in manufacture resulting in a change in the product. I guess most people wouldn't have noticed, but Rick did. He also used to offer 2 different grades of chipping glue. Evidently the manufacturer stopped making the 3x glue that Rick used to sell as glue for fine scroll work. I am not sure how many different manufacturers of glue there are, but I do know there is different glues out there, and according to Rick, some of them won't chip the glass. I always bought my glue from Rick ...of coarse. I know Rick was picky on the glue he bought and sold. Maybe some of the problems people are having is because of the glue. Perhaps Pat mackle could shine some additional light on this topic.
I recently tried some mexican chipping glue that looked quite different than what I was used to using. It worke quite well.

Hello Larry and all the rest:
Well, I had that very same conversation with Rick. The short version of the conversation was the company changed their rating, going from 3x and 5x to 135 (gram strength) and 165 (gram strength). In the end, he just bought the one he wanted to sell and sold it as "glue-chip glue"....forget the numbers.
I somehow managed to get Rick to tell me where to buy large quantities of it...probably because I was doing the demos and classes so he told me. I bought 100 lbs of what I labeled 5x on all my smaller containers. It was the more aggressive version. I bought it from Milligan & Higgins, though after 20 years I couldn't exactly remember the name. Bill Hueg still has a drum of it and when I was talking to him one day, he mentioned Milligan & Higgins--reading it right off the drum near his knee. Rick had told him the same source a long time ago, too.
So, if you want the good stuff, order the 164 gram strength direct from Milligan & Higgins, or maybe Ron at Letterhead Sign Supply has it in smaller quantities. It runs about $3.50 per pound in the 50 lb drum, plus shipping. One drum will last everyone I know (except Pat Mackle) a life time.
To follow all this up, my old 5X glue was a dark green color. Rick sent some glue to Boise for our class and it was a lighter tannish green. It didn't chip nearly as quickly as our deep green glue, mixed at the same time in the same conditions. I can confirm THERE IS A DIFFERENCE in some glue, even the glue sold for glue-chipping. I'd buy the 164 strength again, knowing I can calm the glue a bit with glycerin if needed.
For people wanting to "play" I heard over the years that Alum will make it more aggressive. I don't know if problems people are having with the frosted glass has anything to do with the glue. I doubt it really. It seems people "think" it will just all pop off in a systematic time frame, but some of will always be stubborn and take longer. Just keep it "warm" and dry and it will chip if there is a sufficient layer of glue. DON'T USE A HEAT LAMP!!!!!!!!!!!!!!!!!!!!!!

Bob RochonI wouldn't consider it finished (good or bad) unless you broke the glass with the heat lamp. Just squirt some glue on frosted areas and let that chip. You can use asphaltum to control where the glue goes.
There quite a few other posts on this part of the proces in the recent pages.
Mike
Yes Mike, I broke the glass. Oh well, I seem to be learning a ton of the what not to do's quickly. I have 2 more test pieces to do.
Harry Oresko
I've only had a couple of 1/8" pieces not break. Try 3/16"...If you use a heat lamp, it can't be to close. Just enough to keep the glass warm. I have a double quartz heat lamp setup on retractable neck. It swivels also. The kind for working at night...500 watt. Don't move the glass once the glue has set up, it is pulling on the glass. If moved during the ghipping process, it can break. Build a chipping box from raw wood, no paint or varnish. Others have diagrams or drawings of how to build one. Mine is only 5 feet long and 3 feet deep and 4 feet tall.
