To make a silver plated animal box, the artisan has to deal with two different elements: an upper and an inner part which are first molded into the fire.
For the upper part, the copper leaf is cut following a matrix and is then pounded until it gets the form of the animal, head and back.
Same process for the inner part: the leaf is cut as a cross form which is folded up and pounded to get the feet, and the stomach form.
The inner and upper elements must fit together perfectly.
