Actually John you're not far off in your Bud comment. After final DI rinse follow with two alcohol rinses. One to displace the water and the second to provide a fast evaporating rinse media when placed in the oven. Use a good grade, electronic or above isopropyl alcohol. Better yet 190 proof ethanol and start the weekend out right.

I guess havng removed it, the rinsing and drying wil have to be carefully addressed to avoid re-oxodising the silver, maybe several agitated rinses in DI water followed by heating in a nitrogen purged batch oven. As for the rinsing material as it is Friday my suggestion for an alternate is Bud light since it is absolutely tasteless/odorless...........8-) John ------------------------------------ Avanex John Burke Senior Manager RoHS Compliance [log in to unmask] 40919 Encyclopedia Circle Fremont CA 94538 tel: 510 897 4250 fax: 510 979 0189 mobile: 510 676 6312 ------------------------------------ -----Original Message----- From: TechNet [mailto:[log in to unmask]]On Behalf Of R Sedlak Sent: Friday, October 21, 2005 1:33 PM To: [log in to unmask] Subject: Re: [TN] Removing oxide from silver flakes. In the US, I would send you down to your local supermarket to buy a bottle of silver tarnish remover.... Another way to do this, depending on your situation is to find a mildly alkaline detergent solution, and pour the silver flakes on to a piece of aluminum foil, and immerse in the mildly alkaline detergent solution... this will reduce the Silver oxide to silver metal... Good luck, let us know if it worked. Rudy Sedlak RD Chemical Company Syed Sajid Ahmad <[log in to unmask]> wrote: Any help on getting rid of oxide on silver flakes will be appreciated. Thanks.
