The Twirl Bowl, made of 3-D printed porcelain, creates the illusion that it is twisting as it rises. Clay is mixed before it is fed into the printer to create the textural striations on the surface of this vase, which is a little over six inches high and twelve-and-a-half inches in diameter. While the placement of the color will vary with each of these bowls, the overall design will be perfectly uniform. This vase is not watertight.
