Adriaen de Vries's Bronze Casting Techniques

Adriaen de Vries most often used a technique called "direct lost-wax casting." During the casting process, the wax of the original wax-and-clay model melts out, or is "lost," hence the technique's name. Because the model disappears, each bronze cast produced is a unique original. If the casting fails, the sculptor must begin again. Thus, only the most confident sculptors worked in this method.
