Crackle Vase Solid, TallCrackle and thunder a magical wonder! At Kosta Boda, we marvel at beautifully preserved cracks in glass. The Crackle collection has an expressive, sculptural exterior created using an old handicraft technique where the hot glass is dipped in ice cold water. The crackled surface reflects daylight and reveals its stories of fire, earth, and water. The vase is mouth blown in Kosta, Sweden, and designed by sa Jungnelius.
