    Aging new cedar to look like old...Help

    I'm working on a restoration project for a guy at work. It's an old red cedar blanket chest and I've had to replace a board on the lib of the chest.
    The old finish looks like old dark garnet shellac to me. Does anyone have any tricks to make the new board look like the old boards?
    Thanks & Happy Wood Chips,

    Exposing high tannin wood to sunlight will accelerate aging somewhat.

    The fastest method I've found is to treat a high tannin wood with potassium dichromate...it will instantly age the wood. I used it on a sapele project with excellent results. Comes in crystalline form, mix a very small amount with water, wipe on/wipe off..done. PD requires rubber gloves and a respirator as it is somewhat toxic, but completely safe with proper handling.

    I started with absolutely nothing. Now, thanks to years of hard work, careful planning, and perseverance, I find I still have most of it left.

    Scott,
    Where would I find potassium dichromate locally?

    Dennis, I purchased mine from Shellac.net. The owner, Ron, has decades of refinishing experience including extensive knowledge of potassium dichromate and would be happy to discuss your project with you.

    Alternative would be to add a bit of dye to the garnet shellac.

    Finishing is an 'Art & a Science'. Actually, it is a process. You must understand the properties and tendencies of the finish you are using. You must know the proper steps and techniques, then you must execute them properly.
