Cool Dining is a set of terracotta tableware, that keeps food cool and fresh.
The Cool Dining set is based on the Zeer pot. It is an evaporative cooling refrigeration device that does not use electricity. The Zeer pot is made of two pots: the outer pot is made of porous terracotta; the inner pot is made of glazed clay to keep the food dry and fresh.
The evaporation of the liquid from the outer pot draws heat from the inner pot – just like sweating cools us down.
The device can cool any material, requiring only a flow of dry air and water. The Zeer pot, also known as the off-grid refrigerator, is common in off-grid areas.
