A kulhad is a biodegradable, disposable clay cup used in India by food vendors to serve hot beverages like chai and some desserts like yogurt.
The cups have been excavated from the Indus Valley as far back as the end of the Stone Age, 5,000 years ago.
Lately, synthetic materials like plastic and paper have started replacing these clay cups, as they are cheaper and more convenient for vendors to acquire.
But the clay cups still persist in India.
We went inside a kulhad workshop outside Kolkata to see how the traditional clay cup business is still standing.
