Yes – oxidize. Not stain. Not dye.
Alin Dobra posted a very informative blog on using potassium dichromate to cause wood to darken the same way it does when exposed to sunlight. I’ll let you read his entry to learn about the technique. These stools will eventually be sitting around the island in our kitchen. The sun will only land on the top part of the backs and I don’t want them to develop “tan lines”.
This was my first experience with the technique. I coated the surface twice to make sure I had uniform coverage. You can see how much darker the mahogany is after treatment. The two pieces on the right were just coated.
After the surface was dry, I sanded each surface with 320, 400 and 600 grit.
This process caused me to lay out all the parts at once. These next pictures give a pretty good view of the number of pieces in this project. I had to clean off my workbench just to find space!
The total is 156 pieces of mahogany.
And 24 pieces of maple.
