Water remains cool in earthen pot (calamba or caramba) even in hot weather

Water remains cool in earthen pot (calamba

or caramba Ilk) even in hot weather

Notice that the earthen pot "perspires" because it is porous.  Like sweat it keeps the body cool.  Cooling is the aafter effect of evaporation.  Fannig increases the rate of evaporation, so with cooling.

 

Banga has been the symbol of Calamba (town in Laguna, birthplace of Philippine national hero, Dr Jose Rizal).  It originated from the legend of Calamba which tells a story about two Spanish soldiers, speaking in Spanish asking two native women selling homespun clay pots and stoves the name of the town.

The “Banga” (ba-nga), is a round or spherical jar made of clay, used for fetching water and mostly adopted by the northern region of the Philippines
