The Three-Corner bangle was the first project that was required at the School of Design, in Pforzeim, Germany, which, by many accounts, sets the standard for excellence in goldsmithing skills. The aspiring smith was given a length of sterling wire, a hammer, a bracelet mandrel, and a steel bench block. With those tools he or she hammered out and finished a perfectly porportioned and symetrical bangle. When the bangle was completed the instructor put calipers to the piece and assessed it from every point. If not exactly symetrical the student was handed another length of wire and told to try again. The student did not advance until a perfect bangle was fashioned...no matter how long it took.
