Stilts are triangular. At the apex of each angle there is a point to rest the bottom of the ware on. Stilts are made of very stable refactory material. Cheap, utitarian stilts are made entirely of refactory material. The better, sharper pointed ones have kanthal metal points. Capilary action draws a small pucker of molten glaze during firing, at the point of contact. When the stilt is broken off; it leaves a razor sharp spur. This spur will severely slice a finger tip or palm. Much like a deep paper cut. Wear gloves when unloading the kiln.
