This ceramic object appears to be composed of a unique combination of clay and sand -- based on what is visible to the eye. Whatever the nature of the composition gives the interior fabric an undeniably porous nature. The fabric is tempered with a white and shiny material. The shape of this object makes its overall form and function indeterminate. There appear to be two edges, and the form seems to go from thick (33.64mm in breadth) to thin (20.46mm in breadth).
