“Her collection of cooling Drinks Rocks are handcrafted and come in modern, geometric shapes made from soapstone and marble. Klock, who was working with soapstone for the first time, found that it is soft enough to be formed into a huge variety of shapes. She decided not to plan their exact morphology with preliminary sketches, but let the rugged coasts and breathtaking nature of her native Norway be the inspiration behind the primitive, crude cubes she carved.” -Wallpaper
