Tuanse 4 Pack 1.75 x 1 Inch Tall Round Kiln Posts High Alumina Kiln Posts Ceramic Shelf Supports for High Temperature Kilns Shelf Sturdy Firing Post

I use this 14x2 inch cake pan. It's very solid. I place it on top of the deflectors using these 1.75x1 inch ceramic kiln posts as spacers. I fill it about halfway with water.
