    TeaVivre Glass Teaware Safety Test: Instantaneous Temperature Change

    We tested and recorded the performance of our glass teapots and double-wall tea cups under instantaneous temperature change. We tested tea cups and teapots at -8℃ that were frozen for 48 hours in the fridge and 2 tea cups at room temperature, with boiling water at 100℃. The result shows that our glass tea wares are safe under instantaneous temperature change.
