The general impression given in the books I have read is that the various gums - arabic, traganth, and ? - all burn out cleanly. I have used arabic for holding some fused items and for making sulphides. I would expect it to burn out about 500F, being organic, but I don't know.
i used gum arabic for my copper enameling back in the 70s and have been attempting to re-experiment with it. it does burn off cleanly but not sure if trapped gases might be a problem in glass applications???? m
I have used it for a binder when painting with glass. It has not left anything at all. I did wait until it was completely dry before I fired. I have also used white vinegar which also is a binder and it did not leave anything behind that I could detect.

I went to web site that had a lot of info on gums, shared what I said below, and asked it they could give more info. The reply was that 500F was a good estimate and most gums leave about 3% ash. Given this low temperature and this small ash, I would expect no gas problems at all at
1200-1300F when glass sags and starts trapping air and other gases under it.InspirePoint website is not affiliated with any of the manufacturers or service providers discussed here. All logos and trade names are the property of their respective owners.
