Friends,
I'm hoping someone on the list, with a bent toward chemistry, could help me figure out how to reduce the silver in a ceramic filter ammoniacal silver nitrate and acetaldehyde. Apparentluy this process is identical to what is done with the production of mirrors. But all I have to go by is the four constituents: silver nitrate, ammonia and acetaldehye. I do not know (even roughly) the amounts of each of these. or the steps to follow. Can someone please tell me, even approximately?

I do know that after this reduction of the silver it's important that the kiln firing be in reduced oxygen, in order to get silver metal, bonded to the ceramic. This is great, the silver metal perhaps ten times more effective at killing pathogens than is the case, were I to use colloidal silver, ending up with silver oxide within the medium. Also, why is the reduction necessary prior to the firing? Why not just saturate with silver nitrate, then let the reduction happen in the firing?
Thanks!
Reid
