Charles & Marie are taking pre-orders for the successor to their heat-sensitive “On/Off” mug—this one goes from “Cold” to “Hot” when you add something, you know, hot. Still very pricey at $25, but apparently they sold out of the last ones, so I may not know the going rate for a fancy mug.
They do say that this mug is dishwasher safe, which is good. (I had related my previous experience with heat-sensitive mugs being somewhat fragile in the wash.)
