Is the dark stuff under the bark on a maple slab mold?
I have a spalted maple slab that is solid and dry. No mold on the surfaces. I’m sanding some of the edge to lighten the darkness there. Is it mold I’m removing? I’ve sprayed it with a mold remover, but it didn’t change. The darkness does disappear somewhat along the edge when I sand deeper, but still lingers in other areas. It is darkest where the spalting has those nice black lines.
