So I know there are a few of you UK members out there who work with bone china slip. There are hardly any Americans making and using it and I want to learn. I've picked up my raw materials and have a basic recipe of 50% bone ash, 25% Cornwall Stone, and 25% kaolin but finding out /more/ details isn't easy. The initial firing temps listed are super high at 1400 C (Orton cone 16), too high for my kilns that only go up to cone 10. I understand that adding fritware can lower the firing temps into a more workable range for me of say, 1250 C (2282 F or about cone 8). But I am not having any luck yet finding which fritware to use and how much. Anyone willing to make suggestions or have a bone china slip recipe with more detail that you might be willing to share? I currently have my bone china sculptures produced in England and I coudn't be happier with them except for the expense, and the fact that I may have a 1 to 2 year wait to get pieces done and shipped to me for glazing. I am blessed with a local supplier that carries everything I need - except again, I'm not certain /which/ kaolin is ideal for bone china slip. The one I got to try first is Grolleg English china clay. The Cornwall stone here is more orangey tan than expected and seems to be low in flourine, which I hope won't be a problem.
