The species of wood used in this particular table set is known as worm scarred and mineral stained maple. It is also known as ambrosia maple, because ambrosia beetles infest the maple trees and bring with them a fungus that discolors the wood – very interesting! Some people refer to this wood as ghost maple because often, the beetle holes are situated side by side, and when this happens, the “eyes” within the stain make the stain resemble a ghost. The mineral staining happens when the tree brings up various minerals from the earth, which also discolors the wood. This set is perfect for those small spaces with each chair fitting comfortably within the table like a puzzle piece.
