I have a 22 inch sphere ( weight about 6 lbs. ) that is glazed all over
that I would like to stilt and fire to cone 4. The metal pointed stilts I can
find ( like Roseli ) just don't look big enough to do the job. I am thinking of
getting some Inconel bolts and grinding them to a point and then anchoring
them in drilled kiln shelving. I wonder if anyone has had any experience with
supporting pots in a kiln on Inconel .
I will test before firing a major piece but if anyone has experience or
guidance it will be much appreciated. Alternative ideas will also be gratefully
received.

If you made a sacrificial stand for it, out of clay,
such that it looks like three chopsticks in a pad with
a point on the end of each one...
To deal with weight, make the pads more like three
little pyramids that come to sharp points.
and then bisque that.
Then fit it to your thing and remove just a 3 ml
diameter point in the glaze where it would touch.
Then set the thing on it precisely and fire to cone 4
with a tiny bit of wadding on the end of the tip of
the chopstick,
worse comes to worse, it sticks.
But if it is only touching at a tiny point, you could
break it off and grind it clean.
Best possible case, the wadding works like it should
and it doesn't stick at all.
It sounds like a bit of work, but so does grinding and
setting bolts.
You should let everyone know what you wind up doing
and post a picture. It sounds interesting.

Hi Paul,
Kanthal wire comes in the regular size and also a super size, about 1/8" diameter.
I bought a length years ago from laguna. I made stilts to hold anything by cutting
one inch sections of that heavy-duty kanthal wire and anchoring them in big hershey's kiss
shape pieces of vermiculite-loaded clay.
You can cut your wire at an angle so you have a point to set your work on.
I have stilted very large pieces at both cone 06 and cone 10. At cone 10 I used to use
home-made bisc hershey's kisses.

Paul Gerhold asked about Using Inconel bolts for stilts?
Why not construct a purpose-made stilt/support from clay. You can make
something to exactly suit your sphere in shape and strength. Adding the
little lengths of nichrome wire in the appropriate places should yield a
serviceable support at a much smaller cost than the inconel bolts. Both the
materials are well understood in craft ceramic application, so you don't
really need the adventure of a different material, unless you prefer.
