This might be a really stupid question so apologies in advance. Silverprint is offering this new nifty quasi-cyanotype paper. I read about it in the latest issue of Black+White. It is not a cyanotype kit. It is just paper you expose to sunlight, and then wash in cold water. The article said it is safe for children, but I wanted to know a little more. I'd love to try this out with my 3-year old nephew who loves cameras. But is this really safe? The paper is coated, so I would have thought the paper is toxic. And when you wash it, I would have thought the water is then toxic. Anyway, thoughts? Below is the description from Silverprint.

Thanks
