In India tea is more popular than coffee. If you visit to India you will never find a place without a tea stall. An Indian adventure would be incomplete without the experience of sipping tea at an open-air tea stall, and the gratifying, childlike pleasure that comes with tossing your cup and hearing the �pop!� as you watch it hit the ground and break into bits.
All over India, potters spin these small cups out of river clay, which are then sun-dried, half-baked in an open fire and delivered to local tea stalls. We find the gritty taste enhances the character of the tea. One could even argue that the minerals in the dirt provide the added benefit of a daily multi-mineral supplement.
After use, your tea cup dissolves back into the earth.
These little clay 'disposable' cups are the norm at all the street stalls. Thrown 'from the hump', it takes a skilled potter about two or three seconds to make each one, and when you finish drinking they're discarded into these basket for recycling in one form or another
The size and shape of the cups vary throughout different regions of India. The average clay cup holds about three or four ounces, but can vary from the size of a shot glass in Gujarat to the uncommon, American-sized, 10-ounce tea we found across from the Hare Krishna temple in Vrindavan. On several occasions we enjoyed a small, 2-ounce cup of tea for only 3 rupee (about 5 euro cents).
So, instead of using traditional coffee cup, a clay cup is much better to use.
In addition to being environmentally sustainable, it is very cheap and the materials need to made it is available everywhere. And you do not need any special technology to made them.
