What Are the Best White Stoneware and Porcelain Bodies for Single Firing with the SH palette?

[George Lewter]

I have been using Laguna B-mix5 since 2009 with minimal problems. My Michigan supplier appears to have ceased operations. Does anyone know what body Steven is currently using after attending one of his 2013 workshops. I heard at one point he had switched to a Standard porcelain or 182 which is listed as:

182 WHITE STONEWARE BODY (Cone 6-10)

Near white plastic stoneware body. Good for use with bright glazes. Available with and without fine grog. 
Shrinkage:  11% at C/8, 12% at C/10.
Absorption:  3% at C/8, 2.1% at C/10. 

As you can see this clay is at the bottom of its range at cone 6 and has high absorption even at cone 8, so I'm thinking it might not be a terrific cone 6 body.

I would use one of the Standard Ceramic Supply bodies if possible, as there is a distributor within 50 miles of me. We also have Runyan which is a local manufacturer with a very sophisticated clay compounding facility. But they don't seem to have knowledge of what constitutes a good single firing body.

I emailed Stephen Hill and he told me he uses Coleman Cone 10 porcelain, yes Cone 10 with his Cone 6 firing schedule.
