How do I fire a glazed spoon?

I made a serving spoon of Laguna B Mix 5. I wanted it to serve shrimp salad, thus I used a big shell for a mold. The handle curves back under slightly, and is textured to mimic the shell also. This spoon is bisque, waiting to be glazed, but I have been putting it off because I can't figure out how I am going to fire it once it is glazed!
I have been told to not use stilts with stoneware, as it will warp. Is this true? How can I fire this spoon, so it is usable? I really like my spoon, I am going to be so disappointed if I can't make it functional.

What if you used a stand made for firing beads? You could put a hole in the tip of the handle.... just a thought.

B-mix. isn't that ^6? If so you can use wire stilts, or you can use ceramic stilts. They will leave a small mark that can be ground and buffed out with varied dremel grinders and rubber polishing wheels.

Back when I did production soup tureen spoons at cone 10 thetrick was to wax a small spot where the spoon handle and spoon bowl touch. Thenplace them on a soft brick piece at those two contact points and fire. The softbrick snaps off easy even if the glaze runs and you can grind down the glaze orbrick chunks easier than shelves or hard bricks. Try this and you will see itworks well.

Mark what is soft brick?
You mean low fire clay? would`t that melt if fired too high?

When it comes to fire brick there are many different types-The kind that is very dense and hard and heavy are (hard bricks) Need a brick saw to cut them-then there are the light easy to damage soft bricks -Electric kilns are made of these-these are easy to cut with anything
Soft bricks come in many different K #s which are the bricks firing points and also reflect how they insulate
The k#s I know are
K 23=2300Fahrenheit
k25=2500F
K 26=2600F
K28=2800F
Most electric kilns are made of K 23s
My high temp. car kiln is lined with 26-and 28s as they hold up better than 23s over time at cone 10-11.
I could talk about hard bricks but most here fire in electrics and use soft bricks.
I hope this helps
