I too am searching for some Bluing, but for a different reason. There was a wonderful "Watch Mr. Wizzard" show years ago where he grew crystal gardens on coal using ammonia, bluing and salt (I later added dashes of food color.)

I'd like to show this to kids of today but can't find the bluing. Any help out there!

An e-mail reply as well as a posting would be apprerciated. Thanks. Andy AHEliason@aol.com
