Potassium Iodine and permanent marker?

[Scott Weisman <sweisman@xxxxxxxxxxxxxxxxx>]

Hi group.

I had a student pose an alternative process question for which I  
cannot answer.

Does anyone have an idea of what this student is referring to?

" There was a technique I learned in high school which I'm pretty sure  
is called
photo bleaching. It's where you draw over a black and white photo in  
permanent
marker then let it sit in potassium iodine or some chemical. I was  
wondering if
you were familiar with this technique, and if so, if you could help me  
obtain
the materials I would need and teach me the exact process. I wanted to  
use this
technique in my final black and white photography project."
