What Is C&c?

[christina.b]

While searching for a cone 6 smooth white clay recipe I came across this Val Cushing recipe on Alfred U's ceramics site. I'm not familiar with C&C, maybe it goes by another name or there is a commonly used substitute? Still searching for other recipes.. Ideally bright white, smooth, doesn't warp and is cone 6.

Thanks! - Christina

C&C = Champion and Challenger, a blended ball clay from HC Spinks company. It is my preferred ball clay. Much nicer than OM4.

Thanks for the research! The article goes on to say "considered by some as a stoneware clay, it fires very white and is used in white firing porcelains and stoneware for its excellent plasticity" is there something similar on the market to this? Baileys is my supplier and I don't believe they carry C&C. Thanks!

You could use any ball clay in that recipe and be fine.

I can do sheffeild! It may be worth a trip. I've been trying to buy my dry materials from one supplier for consistency but I go out that ways anyway from time to time. Thanks Timbo!

Everyone should try C&C if they currently use OM4. There is a noticeable difference for the better.
