Is this floating or black spots on the bottom of pan? If it is spots on the pan then I'd say you have niter building up and having syrup get trapped between it and the pan causing it to burn. Ussually will make popping noise. Just a thought

I've always had that in my syrup pan. I figured it was sugar sand.
