A pair of posts, either 1/2", 1" or 2" high. These are only 1" square so they take up less room in your small kilns than your traditional posts. These are a must for stilting the donuts when glaze firing. Also, they are handy to have when you need to fit more items in your shelf. You can purchase additional shelves....see Hard Fiber Shelf in the Firing and Torch Supply catagory.  You'll need 4 posts to place the Stainless Steel Containers for firing BronzClay and CopprClay.  Heat needs to be able to circulate under the container when firing.
