A friend sent this picture, entitled "spot" that I found rather captivating. It is a simple picture of the interior of an Iga bowl of a rich, deep bidoro pool that has accumulated at the lowest point of the piece where the ash built up along the walls and during the firing ran and built up in a centralized point. This natural occurrence is part of why I find both Iga and Shigaraki so fascinating and though this effect can be artificially created, it is rarely done so in such a convincing and serendipitous manner.
