All things creative
Wow! That was interesting...did you research that for your book?
Yes, I did some research on an Indian guy who ate too much silver leafing. I guess they put it on some chocolates in India. He turned blue. I also did research on coloidal silver, which is the liquid stuff that turned this guy blue. There are a few cases of it happening. Basically, too much silver and and salts together can turn you blue.
