Serious Warping

Recommended Posts

maya    0

I made a mission and put a curve in it by drying it over a circular concrete form.  To give it support, I added a base in the back.  When it came out of the kiln, one half looked the same, but the other side warped completely at a crazy angle.

 

Any ideas on how to prevent this?

Having the back wide open is the likely culprit. It needs more support back there. You don't necessarily need to cover the entire back, but having a slab across there will help to stabilize the sides.

Does not stand a prayer without back support .

I could not help myself on that one.

Ha! I get it Neil....... walked right into that one.  Thanks everyone for the info.  I may just go flat----giving it that curve seems more trouble than it's worth.

What if MAya threw a cylinder and cut it in half for her mission?  or a slightly less than half, if you know what I mean. There could be less warping?

Can you glaze it in such a fashion to fire it laying down?

Even then you will need to have some sort of connection across the back/top.

If I cut out my mission outline from a slab and fire it laying flat, do y'all think it'll still warp?  Kind of a "mission-shaped" tile.

Ben I think you would just place a wax resist where your pot will touch the shelf as in any pot. Provided that your glaze is stable there would be no prob.   Just glaze in your usual way. any weight bearing surface in touch with shelf sould be glaze free as normal.
