Corelle gets hot as well. Best bet is glass.

Call the manufacturer for service or replacement.

This.

Except most ceramic dinnerware is glazed and therefore not absorbing water. It’s like a glazed vs unglazed terracotta planter.

I have two sets of crate and barrel china plates. One does this and the other doesn’t.

So if your microwave is heating the plate (which shouldn't, in its atomic structure, contain any water), the appliance is no longer producing the radio waves at the correct frequency. Time for a new one.

THANK YOU FOR THIS INFORMATION!!!!
I called our microwave manufacturer, as I was having this problem. They had me unplug the unit for a few minutes and it recalibrated itself! I was very pleased! Thought you'd like to know.

Thank you for this! We just remodeled our kitchen and have a new microwave that heats up the plate not the food. Our old microwave never did this with the same exact plates. Hopefully this calibration works or I might have to buy another new microwave. Our old microwave was a large over the range type and our new microwave is a countertop unit that sits on a shelf in a wall cabinet and is smaller. I wonder if it has something to do with the size of the microwave.

My "microwave safe" pottery barn plates have been getting hot lately but didn't used to. We moved to a new house and I will now have the microwave checked! Thanks for this post.

My microwave was working 100% , heating food and not the plate, irrespective of the plate type.

Recently it's the other way around. It must have something to do with the micro-wave, I will reply once I've recieved it back from LG.

It's definitely NOT the plate type.

For those of you trying to determine if the problem is the microwave or the dishes, get a clear glass-only dish or cup, like a Pyrex measuring cup, fill it with water and try to boil the water. If the water heats up, then it is not the microwave and likely the dishes. If the water does not heat, then it is the microwave.

I am having the same issue and have used these same dishes for 4 years. I am thinking also that the microwave might be going bad. Please let me know when you find out.

HA. And that explains why I have not been able to find the perfect cup to heat my tea that I like to sip (hot) all day long.

You should get the glass mugs from the poster whose crazy MIL tossed out her ceramic mugs and replaced them with glass ones.

take the plate to work and microwave something there. Write back to say whether it is the plate or your microwave.

Every plate does fine in my microwave!!! Excluding STONEWARE!!! You will get burned...
