A simple and inexpensive vacuum procedure has been employed to grow copper single crystals by the Bridgman method. Crystals grown at a lowering rate of 2 inches per hour have a high degree of perfection as indicated by the presence of Kikuchi lines on electron diffraction patterns. The perfection varies along the length of the crystal, that portion freezing last being the most perfect. It is suggested that this variation in perfection along the length will occur to some degree in all unseeded crystals made by the Bridgman method because of the greater supercooling that occurs when the first metal freezes.
