Sometimes a little grey is good

When facing the kitchen shelves with aged wood, I didn’t want to fuss with mitered joints.  I didn’t think it was necessary.  A small detail however, is that a lapped joint shows a bit of clean, non-aged wood right at eye level.  What to do?

I remembered reading about aging wood using tea, vinegar, and rusty nails.  Having all those items at hand in the cabin, I set to work.  At the time I couldn’t remember the proper order of treatments, and I don’t know if it really matters.  The basic concept (familiar to anyone who works with natural dyes) is mixing tannins with iron to create a black pigment.  On wood, the color is grey and it really does match aged wood.  The surface texture will differ, but for a tiny bit of wood, at an edge, this is a great technique.

In the photo above, you can see the effects of two applications on one half of an aged wood scrap; I used one application for my shelf. I also treated the top and bottom surfaces of the shelves (1/4" plywood).  The surfaces are a smooth grey and match the color of the edge closely enough that the entire shelf seems like one very thick board.

I’ve found a recipe online similar to the one I recall from the past.  If you try the technique, play around with the number of applications of each solution to get the intensity of grey you need.  There is a strong vinegar smell while the wood is moist, but disappears when dried.  The solutions are relatively safe, but even so, I wouldn’t leave them around kids or pets; they can be safely poured down the sink when you are finished.
