Shrinkage

Started building forms for the clay today. In sizing the forms, had to allow for shrinkage. I'm going to assume the EP Kaolin will be the dominant factor so I'm going to use Edgar's data on this. I put that into an Excel file to calculate it and it looks something like this:

	Shrinkage Table for EP Kaolin by Edgar Minerals
	Dry	Fired - Cone 11 (1315 C)
Shrinkage	5.0%	11.8%
Formed 1	2.000	2.125	2.250	2.375	2.500	2.625
	4.750	4.875	5.000	5.125	5.250	5.375
Dry 1	1.900	2.019	2.138	2.256	2.375	2.494
	4.513	4.631	4.750	4.869	4.988	5.106
Fired 1	1.764	1.874	1.985	2.095	2.205	2.315
	4.190	4.300	4.410	4.520	4.631	4.741

The units are inches. The entire table in excel is here.
