I have since used same mug at least 20 times .. and it is back to normal.

# Why would handle only get so hot (way over 100 degrees C)

# Why only the once

# a mate commented that the reason was the handle had touched the sides
of microwave (unknown) ... but how would that make a difference.





Any cracks in the handle or holes needed when the cup was fired? Water
might have got in and boiled.
