So How Do You Glaze The Base of a Ceramic Piece?

Use kiln stilts! Kiln stilts consist of metal rods that prop up a pottery piece off the shelf, and a durable one may be used multiple times. According to pottery suppliers, beyond cone 6 (1240°C), metal rods may begin to deform, and may deform at lower temperatures under heavy weights, so stilts are best used for light-weight pieces. You can also increase the number of stilts to spread out the weight distribution, but this will result in more places requiring sanding after it is fired.

For firing spoons, use straight line stilts if available, or you can also try the three pronged ones under the bowl of the spoon. Fired at cone 5 (1200°C) you shouldn’t have any trouble with slumping, although at cone 6 (1240°C) spoons could bend in the middle. To avoid this, you could add an extra stilt to support the middle.
