I have a question about using iodine on gold. I have some gold with
a pattern that I would like to highlight. So, I would like the stain
to be in the, for lack of a better description, lower part of the
pattern, leaving the higher part of the pattern unstained.
How would I go about this? Do I dip the gold in iodine and wipe it
off? Or do I have to paint iodine in the areas I want darker?
