A friend gave me two 6’ pieces of carmelized bamboo recently.....his wife had been saving it under their bed for the past 20 years after they had a new kitchen floor installed in their home, just in case they needed to replace any damaged boards. It seems that this type of bamboo is heat treated, causing the sugars in the wood to turn brown and harden. Under a dissecting microscope (former science teacher) there are no visible joints in the boards and the pores do appear to be filled. Anyone had experience milling this type of bamboo into tapered lams for the cores in bows? Richard
