This is a very interesting piece.  It has 8 sides..is 7" in diameter and is just a little over 1" deep.  It is hand glazed with two fish in the bottom.  The lighter accents are raised. There is no info on this piece.  No info on microwave, dishwasher, or oven.  It is glazed inside and out but not on the bottom.  Perfect for serving or for your wall.  Great for collectors.  Looks just right to me.      

  Let me know if you want additional photos. Any white spots are from the flash.
