    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.
