Kris,

Unless your goal is to help them into the hereafter, I would use Potassium
ferricyanide rather than the deadly potassium cyanide :-)

Sorry I don't have a recipe, but if you want to simplify the process why not
buy precoated paper and fabric from http://www.blueprintables.com/. I use
these products with elementary and middle school students quite
successfully. You can also buy a small subset of their products through
Freestyle http://www.freestylephoto.biz/. Both are likely to give a discount
for schools

Subject: cyano recipe

hey all--
anyone have a basic cyanotype recipe that uses baking-type measures
rather than weights? (I.e. 2 tbsp. pot cyanide + 4 cups water; 1/2 cup
ferric ammonium citrate + 4 cups water)

trying to help out some high school kids...

many thanks
