My outter vessel holds 14 ounces so I microwave it for 1 minute in an 1100 watt microwave. Stays hot for 3 passes easy. Since my shave den is the laundry room that also has a bathroom sink and throne, it's also right next to the kitchen. I've been doing it that way for 2 years and it doesn't appear the microwave is having any ill effects on my ceramic scuttle.
