This photograph shows a Bubinga bowl. Bubinga comes from South America, and it can be a very large tree. I've seen Bubinga boards 5 feet wide and 30 feet long. While this bowl was made from rings cut from a single flat board, it was not segmented prior to cutting the rings as are the other bowls shown here. I currently have several Bubinga bowls in inventory.
This bowl is made from Wenge and then bleached. The wood is alternating bands of dark brown or black with a lighter brown. After bleaching, the lighter brown becomes a light gray or white, while the darker wood remains essentially the same color. Because the bleached Wenge reminded me of primitive African art, I used a satin finish to keep it from looking too refined. I currently have several bleached Wenge bowls in inventory.
