The design agency Remember the Lion came up with the nice idea of covering bottles with a special concrete based surface. During a house renovation the guys were fooling around with the leftover concrete and dipped an empty bottle into it. They forgot about the bottles, but after a few days they realized that it dried and stayed on the glass, forming an interesting surface. Of course it was too heavy and tainted their hands, but they started to experiment with the concrete, and the result is this intersting and new bottle.
