In digging around through some of my stuff, I stumbled across these.
_David Leach Porcelain_
Matures @ 2280-F/1250-C
Standard China Clay.....56%
Potash Feldspar............25%

Matures @ 2340-60 F/ 1280-90 C
Eckalite #1 Kaolin.....30.0%
Bone Ash (natural).....45.0%
Potash Feldspar.........22.8%
Silica............................2.2%
One would need to experiment to find a local sub for the Eckalite #1
which is an Australian product.
