Material: |
Stoneware mug with normal decal ,AB grade . Size: dia.: 8cm, Height.: 9.5cm
This mug, covered with heat sensitive pigment, changes from black to white (or vice versa) depending on whether it’s full or not, and how full it is. Furthermore, it also shows ‘on’ or ‘off’ as you fill it, or gulp the coffee/tea down. This, of course, comes in handy in preventing spills as you can tell which mugs on the table are full and which are empty. However, since the pigment is activated by heat, don’t expect it to work at room temperature |
