I found it ---
MEL'S COFFEE CAN PORCELAIN:
one coffee can of epk, ball clay, feldspar and silica.
of all the recipes out there for porcelain clay...slip...that
old alfred 4x in my view is the best.
throws well,
fires white,
makes a great slip.
easy to make.
one coffee can of epk, ball clay, feldspar and silica.
and, don't tell me it is not white...it is.
and it fires to cone 11 really well.
simplicity, what a concept. or, as i say...white is white.

Sorry, but this is a screwy transmutation of the old 25-25-25-25 porcelain
recipe.
This recipe is meant to be measured by weight, not volume.
If this is mixed by volume it will be way out of proportion, with entirely
too much
feldspar and silica (heavy dense materials) and too little clay (light
fluffy materials).
By weight, you would end up with something like, I would estimate,
30-35% feldspar
35% silica
15-20% kaolin
15-20% ball clay
With about two-thirds non plastic materials, this claybody would be
next-to-impossible
to work with.
I do use and endorse the recipe if it is properly formulated by weight.
