Add artistic flair to your woodturning with Ambrosia Maple (Acer rubrum) bowl blanks. Also known as wormy maple, this distinctive hardwood features unique blue-gray stain lines and small pinholes created naturally by the Ambrosia beetle. The beetle burrows into the tree, introducing a fungus that produces the striking discoloration patterns that make each piece a one-of-a-kind work of art. These blanks are stable and ready to turn into stunning bowls, platters, and decorative vessels that showcase nature's unexpected beauty.
