I have been experimenting with slip casting white clay bodies and I can't seem to make a slip that will work the way I want it to. Does anyone have a good cone 6 porcelain slip recipe that they use? I would like one that does not crumble when you cut it, so I can alter the lips of the pieces and also carve on them. Also, it does not have to be extremely transparent since I will be glazing the objects. Thanks!
