These pieces did not go into the kiln.
At cone 5 pieces glazed on the bottom usually don’t do well. They fire to 2167 degrees in this kiln. These larger pieces will likely warp over the little stilt you have under them.
These guitar necks will almost for sure warp down enough they will end up melted to the kiln shelf with this little little stilt supporting only the body. We really can’t fire anything we believe will stick to the kiln shelves.
For best outcome you should use a wet sponge and clean ALL glaze from the bottoms and leave 1/8 inch unglazed at the side bottom to allow the glaze expansion in the heat of the kiln.
If you must have the bottoms glazed for this project you need more support under each of them and be aware they will likely warp if not fired flat.
