How to Make Cherry Look Old: There’s No Good Way
It would be hard to find a question in woodworking more often asked and more often inadequately answered than how to make cherry look old without blotching. How many magazine articles have you seen with titles proposing to give you the “secret” to doing exactly this? The reason you are then disappointed after reading the article is that there is no secret. There’s no good way to do this.
The rust-red coloring in old cherry develops over many decades from oxidation accelerated by UV light and possibly also by an original application of linseed oil that has darkened. You can get part way to this coloring by exposing cherry to sunlight, but only part way. You can also get part way by applying boiled linseed oil, and the wood will darken more as it ages.
But to get all the way, you have to use a dye stain or chemicals such as lye or potassium dichromate, but these colorants cause blotching in most cherry. Furthermore, the dyed cherry will continue to darken over time, probably leaving you with a color darker than you wanted.
You may have noticed that factory-finished cherry furniture is darker than old cherry and also not as vibrant. Factories fairly effectively avoid the blotching problem by using toners and glazes to create the coloring in the finish rather than in the wood and this muddies the appearance of the wood. If there were a way to recreate the color of old cherry without blotching, you can be sure factories would use it because of the beauty and popularity of this wood.
So you have a choice. You can give new cherry the coloring of old cherry, but you may have to live with blotching depending on the specific boards you’re using. Or you can color cherry and avoid much of the blotching by putting the color in the finish using toners and glazes. But the cherry won’t have both the color and vibrancy of old cherry.
Or you can let the cherry age naturally.
