These temperature sensitive mugs have a gauge that appears bright when you pour a drink hotter than 36 degrees Celsius (96.8 Fahrenheit) .Thus you can avoid unexpected tongue burns by checking this gauge before having your hot beverage.
They should not be microwaved and avoid direct contact with sunlight.It's better to wash it by hand because the sensor can be harmed in the dishwasher.
They cost around $20-$30....!!!
