savage mary Posted November 4, 2010 Report Share Posted November 4, 2010 Okay this may sound really stupid BUT I make sculptures that are glazed on both sides two dimensional... that are used outdoors, I was fireing low fire and found they did not last in the weather elements...chipping etc. so I went to cone 6 and am finding a lot of slumping with both the wire stilts and the clay..... A lot of lost work not to mention shelves... does anyone know what I can do? Other products on the market that would hold up my work without embedding itself in my work?

bciskepottery Posted November 5, 2010 Report Share Posted November 5, 2010 One option would be to bisque fire the sculpture to Cone 6, then do a low-fire glaze. Bisquing or firing the unglazed sculpture to Cone 6 would allow the clay to vitrify (assuming you are using a Cone 6 claybody, not a Cone 6 - 10), which would make the item more resistant to weather. Glazing at low-fire would avoid the stilt and slumping issues. Link to comment Share on other sites More sharing options...
Marcia Selsor Posted November 5, 2010 Report Share Posted November 5, 2010 Have you done freeze proof test on the clay you are using?Maybe you need to rethink your process. It doesn't sound practical. Would vitrified slips work as well for color? Marcia Link to comment Share on other sites More sharing options...
Deb Evans Posted November 9, 2010 Report Share Posted November 9, 2010 Things to try, glaze lighter on stilt side, sounds like you've got too much glaze on the bottom side and add more supports to prevent slumping. If these are thin flat kind of shapes you could try standing them upright ( don't glaxze edge, or glaze and wipe off) , build a stand for them . Sometimes you have to make your own stilts w/ nicrom wire in clay pads, sharpen 1 end of the wire, other end set into clay, fire them before you use them. Go w/ Marcia's suggestion and then cold finish w/ a polyurathan finish. I live in snow and ice weather so I always tell folks to winterize the work by taking it indoos or wrapping it up.

Claire Tietje Posted November 12, 2010 Report Share Posted November 12, 2010 Hi, Mary. I've made my own stilts that work at cone 6. I used heavy gauge nichrom wire and clay with sand mixed in it. I made some with three prongs and some with four. They work fine. Try to make the prongs all the same height. Happy firing! Link to comment Share on other sites More sharing options...
