The concept of cooling water using terracotta pots is an age old technique dating back to ancient times in India. When exposed to the sun, wet terracotta generates latent heat which rapidly cools the surface, resulting in naturally cold drinking water. Due to lack of electricity in rural parts of India, this method has been used by villagers across India since time immemorial. Mati is a sustainable cooling mat designed for scorching summers in rural India. Among rural Indians, it is common to work, rest and eat while sitting on the ground. But during the peak of summer, sitting and working on the ground often is unbearable. Mati provides a solution by sewing a set of terracotta balls onto a rubber mat using nylon thread. When water is sprinkled on the mat, the surface becomes cold and comfortable for sitting. The excess water is drained out through nine small perforations in the rubber mat. This process keeps the mat cool for several hours. Since it uses readily available local resource materials and simple techniques, Mati can be made locally by villagers themselves.
