How much higher ? What do want to do with it? The proposed use will have some effect on the formula. You could use a porcelain formula. Newcomb Ceramic Whitewares Pitman 1947 pp 230 Table 10-2 gives the following in %ages Kaolin 50, Flint 25 and Feldspar 25.It is fired as high as 2650 degrees F. Newcomb gives the recipe for a number of bodies firing up C14. How do you intend to fire them ?I need clay formula to withstand temp. higher than cone 10.

Hope this helps,

Thanks.....I want to make a rod that I can stack sculpture on and would hold up at 2245 F (about cone 6) without bending or breaking. Would this work..Do I need to fire it higher than 2381 F in order to be solid.?

Have you considered using shelf props ? They are available in a number of lengths and are designed to stand up to many firings at cone 11 12.

Check out McMaster-Carr for all kinds of useful things. They have ceramic tubes in various sizes with service temperatures of 3100 degrees F. http://www.mcmaster....-tubing/=6skfyd
