- Two different ceramic coffee mugs heat up drastically different, why?
Main Question or Discussion Point
I have two coffee mugs (I have many more, just not in this example ). I often microwave cold coffee from earlier in the day. Mug "A" when microwaved for a minute produces hot coffee and a warm outer mug. Mug "B" produces hot coffee and a lava hot outer mug that will give you third degree burns on your hand . They look fairly similar. I am pretty sure they are both ceramic. The only obvious difference is that mug "B" is much lighter in weight.
