the sulfur dioxide or sulfuric acid tone rainbow silver coin?

speculations and combinations of certain chemicals the tone of a coin to a rainbow color and I'm looking for the best combination and mix to make this work in a personal collection of silver coins 90%

I had a friend who tried this with mixed success. Coins wrapped in wet tissue. I do not remember the chemical used. Silver readily reacts with sulfur to form a black spot of silver sulfide. If the layer is extremely thin, it becomes semi transparent and produces the rainbow effect. Silver tarnishes when food produces hydrogen sulfide gas. Things like eggs will generate a certain amount of it. If decay, they produce a lot and this is why it is called "egg gas Rotton. "Hydrogen sulfide forms a weak acid when dissolved in water. Some old water pipes that smells like eggs Rotton the sulfur content of hydrogen. A less smelly sulfur source is sodium sulfite. This is a salt of sulfur and I think the photo shops could sell this chemical. Not much more dangerous than common table salt. A solution of it will react with silver, forming a coat of gloss black. If the concentration of sodium sulfite is very low, the layer of tarnish will be very thin and this could produce colors of the rainbow. The trick will be figuring out how much to add. I suggest experimenting with some pieces of lesser value of silver. If too dim forms, just delete with an anti-stain as "tarnex." The reaction of sodium sulfite and silver is likely to produce caustic soda as a byproduct and breaks down the tissue. Hydrogen gas is the product of others. It is flammable, but not enough there will be the creation of any fire hazard. It's caustic soda that can burn skin, so use lots of water especially after the sulfite Rince Treatment. Sulphur di-oxide and sulfuric acid much more dangerous than sodium sulfite. Sulfur dioxide smells horrible and can even be toxic if it accumulates in a closed room. Sulfuric acid can cause some nasty burns, especially concentrated form. The acid also getting warm water is added, so it is always added to water in its place. I do not think the acid or silver oxide is blurred though. The sulfur is oxidized and it will stay in conjunction with this Instead of combining to produce the silver tarnish.
