I have some white stoneware slip that I bought from my clay supplier, I just want to know if I can add black iron oxide to it to get a black fired clay, and if I can do that then how much oxide do I need to add to get it really black?
So I have a bucket of black slip that I made out of some clay and it is in a thick "pudding" state. I want to thin some of it for brushwork or dipping. Knowing that if I add more water to this I stand the chance of it settling out or being too thin. Is a deflocculant the answer to keeping it suspended and at the right viscosity / specific gravity for application. I want to keep some of it thick for spreading and texture though. Thoughts?
TS Studio posted a topic in Studio Operations and Making WorkOur studio has tested small batches of cone 10 black porcelain for oxidation. We have neither the space to store, nor the production rate to justify a full ton minimum order from any of the large scale clay producers. We do not have the equipment to mix ourselves and mixing small batches ourselves by hand is proving to be too time consuming and labor intensive... so we would like help from someone with a mixer to make a medium sized batch of clay. Can anyone recommend any resources or private studios who take medium scale orders for custom clay blends of about ~150-300 lbs? Our recipe uses mason stain #6600, so I imagine it would be helpful for the producer to have an easier to clean bluebird mixer. Thanks for your help! Ps- Quite obviously, we would also be very interested to know of any clay producers that make a true black cone 9/10 clay for OXIDATION firings. I can't find any that are meant for cone 10, just Aardvark's cone 5 "Cassius basaltic".
