with pretty much any clay recipe, the "whiteness" achieved will have a lot to do with the types of clays you put in the batch since there are varying degrees of whiteness for different ball and kaolin clays. also substituting different things may work for you if you want whiteness - try subbing EPK with something like Grolleg or Tile6.
i tested the following recipe a few years ago and it was just alright, but worked OK for a "white clay body" vs calling it porcelain.
30 Neph Sye
5 Gerstley B
2% plasticizer (veegum, bentonite, macaloid, etc)
what clay bodies have you been testing?
