Yes, I think that method just might introduce too many variables into the process, particularly since repeatability under field conditions is going to be such a concern.

I think I confused Celsius and Fahrenheit on that one. In that case, do you think ground silver included in the grog before the first firing would be suitable for the filters? Maybe it would be cost prohibitive though, I am sure that CS would be cheaper. Gary Gary: I really think the clay filter production process has to be reduced to as few operating variables as possible. After that, microscopic analysis (to determine the phases of silver) of clay samples corresponding to extreme values of these essential process variables would be the next step. Under such circumstances, the first thing I would want to find out is, (1) the form(s) of silver, (2) their respective PPM, and (3) the particle size distribution of each. A possible second step would be regression analysis to determine if certain process variables are relatable to the silver characterization determined in the first step. Roger
