Can you melt a eraser in a microwave?

According to my experiment to try to melt a eraser in a microwave oven, it failed. I put the eraser on a paper plate into the microwave and set it for five minutes. Unfortunately it failed by only getting warm. It may be a good idea to try it for longer, but it will most likely not melt because there is no radioactivity. With that the microwave allows the eraser bits to melt. But without it, heating an eraser is no good.
