Granit Vase 2800 BC Egypt bottom balancing
Previous Image | Next Image
Description: This one piece is so flawlessly turned that the entire bowl (about 9" in diameter, fully hollowed out including an undercut of the 3" opening in the top) balances perfectly (the top rests horizontally when the bowl is placed on a glass shelf) on a round tipped bottom no bigger than the size and shape of the tip of a hen's egg.

This requires that the entire bowl have a symmetrical wall thickness without any substantial error! (With a base area so tiny - less than .15 " sq - any asymmetry in a material as dense as granite would produce a lean in the balance of the finished piece.)
