Why do heat sensitive mug not work any more?
« on: 19/12/2014 16:30:01 »
Teresa Jill Gos asked the Naked Scientists:
   
I read your answer on  how heat-sensitive mugs work and understand the concept.  What I don't
understand, though, is why my mug no longer works.

What do you think?

If the mug coating has organic chemicals, they can degrade over time, when exposed to heat, oxygen and water...just the type of environment you would expect for a mug.
