Mr. Rawles:
I have always felt that Prussian Blue [as mentioned in SurvivalBlog on August 27th] should be part of one’s system of NBC protection but never had the info needed to make it happen until P.H. kindly provided important details. I checked the link that was provided to obtain the powdered Ferric Ferrocyanide and noted that their web site indicates it is “made from Ferric Ferrocyanide”. That doesn’t necessarily mean it is chemically pure. I inquired, and they indicated they cannot confirm the chemical analysis as the product was obtained over ten years ago and don’t even know the manufacturer. Further searches were futile as chemical suppliers seem to be only selling wholesale to other industries. Does anyone know of a chemical supplier to the public of small amounts (a few ounces) of demonstrably clean Ferric Ferrocyanide? – B.F.
