Very good research Brian. Very Informative. Yes the Glazing is from the crystalizing of the pad material on the rotor this is correct. The Pad material Becomes Gaseous when it exceeds it's operating temperature. This is when you get your Brake fade the harder you push your brakes the More of the material that becomes gaseous. Then Just like you said the material Crystalizes onto the rotor and pad surfaces this is most commonly Referred to as Glazing (what we have been talking about). I was Mearly Simplifying my explanation of Glazing earlier. I have taken pleanty of brakes apart to see the Fissures you referred to in the pads caused by the material overheating, these pads also tend to have glazing on their surfaces. this is most commonly seen when brakes that were not intended for this level of performance are pushed well past their limits for long periods of time.

However I would have to remind a few people that Slotted rotors do not share the same tendencies to stress fracture as drilled rotors do. Which makes them better for racing than drilled or combo drilled/slotted. There is no real heat dissepation benetits of having slotted or drilled rotors, that is achieved by having More rotor material to soak up the heat. The only purpose of drilled or slotted rotors is to evacuate gas from between the pads and rotors. And that my friends is what we want to accomplish anyways.
