#alcarraza

• Alcarraza — A rare graphic variant found in old technical literature for the noun 'alcarraza'; a porous, unglazed earthenware vessel traditionally used in the Iberian Peninsula and Latin America for cooling water. Its operating principle relies on the latent microscopic evaporation of the liquid filtering through the vessel's porous walls, which lowers the temperature of the remaining content.
• Alcarraza — A highly porous, unglazed earthenware vessel of Spanish or Moorish origin, utilized specifically for keeping and cooling drinking water. The cooling effect is achieved through the physical process of evaporation of the water that sweats through the clay's microscopic pores, lowering the temperature of the liquid inside even in extremely hot climates.
