I just want to show some unusual spalted black walnut. I have had some discussions on fb over if this is walnut. I assure you that it is as i have harvested personally. Processed some and let some sit a while and this is result.
This black walnut spalting is new to me. Normally I see it much a darker grayish black color with lighter streaks and not the reddish brown like your sample has.
I like the dark brown with black stripes. I'd turn it into reel seat inserts or a cribbage board. For reel seats I use 1"X1"X4" blanks. I can cut it myself. For a cribbage board I need at least 5" X 15" X 3/4".
