In making foot rings for Bear Ware mugs I ended up with many discs of clay that were just crying out to be used for something unique. A dizzying haze covers the next hour of ceramic creation, but when I came back to myself, the Cog Bowl (or Anemone Bowl or whatever you want to call it) was born. I have no idea what you'd use it for. But it is lush! 110mm diameter (including fins) x 50mm. This one has been dipped in two different shades of blue - you can make them out in the product images.
