Three drinking containers: 1. The botijo. The botijo Although the appearance of household refrigerators and insulated containers has lost prominence, the botijo was part of daily life in Spain until a few years ago. It is a container that not only serves to transport and store water for human consumption, is also capable of lowering the liquid temperature several degrees in a completely natural way,in dry and hot climates like most of Spain. Basically consists in through the porous wall of botijo the water evaporates using this energy takes the remaining water, thus lowering the temperature. This process is called evaporative cooling and is very similar to that used by the wind towers to cool buildings in central Iran. With botijos, as with porrones and botas de vino, you drink without touching with lips the container.This undoubtedly created a barrier to the transmission of certain diseases spread by oral contact ( Básicamente consiste en que a través de la pared porosa del botijo el agua se evapora utilizando para ello la energía que toma del resto del agua, descendiendo así la temperatura )
