Via Treehugger:
Most of us are familiar with the bane of plastic water bottles and how they end up in our landfills and pollute our oceans. Collaborating for Spanish design company La Mediterranea, designers Alberto Martínez of CuldeSac, Héctor Serrano and Raky Martínez turned to traditional Spanish terracotta to find inspiration for this vessel which actually cools liquid down and yet is playfully shaped like a plastic water bottle.

Fashioned after the old Spanish “botijo” earthenware jug, MocoLoco transcribes La Siesta’s description:

The vessel is handmade in the traditional Spanish way. The special white terracotta made with salt from the region of Agast keeps the water cold even when the sun hits it.
