A Sycamore tree, often called an American plane tree or buttonwood tree, can grow to a massive size and grows in riparian and wetland areas. Sycamore wood has a rather plain appearance with some flecks. However, when the wood becomes spalted it becomes quite attractive. Spalted wood is wood that is in the process of rotting and has a bunch of fungi in the wood. The fungi makes lines pen-like black lines, in Sycamore, and results in some wild looking figure. The Spalted Sycamore I use has lots of pen-like black lines and came from a saw mill in South-Central Pennsylvania. This particular piece provides a nice contrast to the Walnut Burl.
