Iodine as a stain? Other alternatives?
I've been playing with alternative coloring looking for some interesting results. I am getting some more traditional dyes, but one of the experiments that I tested out that is working out nicely is iodine. I bleached the wood, sanded fine, applied iodine, sanded, more iodine, etc., till it came to an interesting orangy color, then rubbed in with tung oil. and terry-cloth buffed.
The result is nearly iridescent, and on a pretty common piece of walnut. The grain is showing nicely. I'm considering doing some additional testing by layering some dye of another color, sanding back, applying more...
But what I don't know if there is a reason NOT to use iodine?
I've done some experimenting with the following and wonder where I can find more information about alternative finishes.
* pureed tea leaves as a paste to impart tannin (like a tannin mask), and vinegar/brillo to black the tannin
* torching to burn and cook (some interesting results with sugar/carmelizing that regretfully could not be sustained)
* charcoal rub
* gentian violet
* india ink
Considering I have been thinking about wood finish for about a month, and woodworking has been around for centuries, there have to be some good sources for alternative finishes... or does it really end with stain, dye and laquor?
