    Chemical for treating Oak

    I was watching an old "flea Market Flip" last night and one of the projects was a painted Oak cabinet that the contestants stripped down to refinish. To top turned out to have been replaced at some time and didn't match the rest of the cabinet. One of them used a chemical compound that went on purple and chemically aged the new Oak to match the original. Unfortunately I couldn't understand what he said the name was. It was chromium (something) but a net search didn't turn up anything. Figured I would tap into the vast knowledge on here ad see if anyone knows what he used. I have a repurpose project coming up that is an old oak mail sorting cabinet that I am going to make small bins to go in all the pigeon holes. It would be great to be able to easily get a close match between the cabinet and the Oak facings for the bins witout the trial and error process of matching stains.

    Just guessing of course, but I know ammonia will darken oak. I've read of ammonia 'fuming', but don't know about applying it in liquid form directly to oak.

      I've done fuming but that takes a lot of time. This was a quick process.

        It's a potassium dichromate finish.

        Potassium Dichromate is a water soluble chemical stain that reacts with the tannin in wood, and accelerates natural aging and darkening.
