    If you value your health do not do this. Polyurethane which is the
    resin system in Gorilla glue breaks down when heated into an
    isocyanate vapor. Breathing isocyanates is deadly, do you remember
    the Union Carbide plant in Bophal India that killed so many people?
    That was an overheated isocyanate reaction that produced that
    poisonous gas cloud. Use hide glue for granulation not synthetics.
