"A friend of mine who makes violins once loaned me his "ozone box" setup. I used it to stain a boxwood clarinet (Basset Horn actually) that I made back in the early 90s. The stain on this turned out quite lovely - check out this image:
The setup is really quite simple. You set up a transformer such as is used for neon signs, rated at 110V that steps up to 9000V. Attach a plug in on the 110V side. To the 9000V side you attach two heavy wires, insulated - say 6 gauge. These then go into a plexiglas box from opposite sides and then approach each other. The last 4-5" of insulation is removed from the ends of each and these are arranged so that a continuous spark will be produced. A simple fixture is used to hold the woodwind pieces somewhere in the box but not too close. The spark causes two separate chemical reactions in air to take place: the formation of ozone as well as the formation of HNO3 (nitrous). You run it for a while - taking care to keep upwind of this thing. For some reason the addition of some moisture inside such as a damp paper towel helps. I would keep a respectful distance from the device (don't use it while its raining!) and certainly do it outside on a flat, dry surface.
Basically the surface of the boxwood gets oxidized by the O3 and HNO3. The wood underneath remains unstained. A neutralizer such as a baking soda solution or smelling salts applied afterwards will stop any reaction. My limited experience with this is that it produces much better results per my experience than acid staining. Also, I don't like having nitric acid around!"
