Why do Flakes not melt in the microwave?

Why do Flakes not melt in the microwave? Although Flake is made from milk chocolate, the manufacturing process gives it a different arrangement of fat and cocoa solids, so the melting fat isn’t able to lubricate the cocoa particles to the point where they can flow. In a bain marie, a Flake will never melt. In the microwave, it eventually just burns.
