I have used the glue with water and copper as a binder for granulation. It is good for that. It burns out in the firing process.
You really don’t want to do that. “Gorilla” glue is polyurethane
based, and it can produce some very toxic compounds when it burns,
including isocyanates and hydrogen cyanide. Here’s the MSDS from the
Gorilla Glue site, if you don’t believe me: http://tinyurl.com/e6u27
Hide glue, the use of which was discussed here recently, would be a
much better choice for a granulation adhesive.
