Spalted Sycamore

Spalted American sycamore · Platanus occidentalis

This kiln-dried domestic Sycamore is heavily spalted. Spalting is an artifact of early-stage fungal decay (not to be confused with rot). This wood is effectively even softer than it’s hardness suggests due to the spalting, and requires stabilization for turning.
