RE: Homemade Ollas: Thinking About Water Use in The Garden Part 2
I used to see Olla (in Arabic Ollah) at my grandparents'. But instead of being used in agriculture, They were being used for cooling and filtering drinking water. The water is poured into the ollah which is placed in a large pot. Then you drink the water that seeps to the pot. It used to taste fresh and cool even in hot summer.
They were being made of burnt clay and it is said to be first used by Pharaohs. I don't remember seeing any of them over almost the past 20 years, except for a visit to Fayoum Pottery school where they are produced for decoration.
