Heating times are written on your thermal core and on the instruction leaflet. Simply remove the fabric cover and match the strength of your microwave to the heating time. Please note, the times listed assume your Hottle is at room temperature (approx. 70F) - if it is warmer, we recommend heating in 15 second increments and testing to avoid overheating. If it is colder that room temperature, heat for the recommended time, test, and heat further in 15 second increments if necessary.
