Reid, thanks for clarifying your filter manufacturing process - certainly rules out silver nitrate. As for the dangers of protein stabilized CS, there probably are none as far as use in your terra cotta filters are concerned, since the CS is adsorbed - held in place - within the porous ceramic structure. The argyria scare always seems to come back to oral or nasal use of either silver nitrate or msp (mild silver protein - Biopur and Microdyn would come under that category). Whether msp actually has caused argyria I don't know, but by previous accounts it is much less effective - according to Mark Metcalf approximately 15 times less effective than for pure CS (presumably with particle sizes equal).

So CS is applied after the last firing and before use of the purifier...... ......As to the protein contained in Biopur and probably Microdyn, I'd like to know what insight you may have about any deleterious effect due to this material. I haven't seen anything on the list indicating this is a problem. Reid -- The silver-list is a moderated forum for discussion of colloidal silver.
