Cold-Bend hardwood is actual hardwood that has been subjected to carefully controlled, but intense longitudinal thermo-mechanical compression. It has been engineered to be extremely flexible, so long as it is moist. Once cold-bent by hand – or with jigs, clamps and fixtures – Cold-Bend is dried to fix the shape.
How do you make balsa wood bendable?
Submerge the balsa wood in a container filled with a mixture of equal parts warm water and ammonia. Allow it so soak for at least an hour—longer for thicker pieces. This solution breaks down the balsa at the cellular level and is thus especially effective in making the balsa wood more flexible.
