Can my KeepCup go in the microwave?

The glass, silicone band and polypropylene plastic cups (pp No.5) can go in the microwave and be heated to 100 °C / 212 °F. 

These components should not be placed in the microwave, because they may be damaged if heated over 100 °C / 212 °F:

  • Lid & plug
  • Clear plastic cup
  • LongPlay Band & Clear Plastics Booster
  • Cork Band


Rapid temperature change or heating over 100 °C / 212 °F may cause the glass cup to shatter. You cannot heat liquids in the microwave above boiling point, or put a cold cup in boiling water or microwave.
