Class Code Information


Jewelry Mfg.


Code 3383 applies to employers engaged in manufacturing complete jewelry items such as rings, earrings, necklaces, cuff links and bracelets.  A sketch of the design is drawn on paper.  A copper or wax model is made. Rubber is wrapped around the model forming a permanent mold.  Melted wax is poured into the mold and allowed to cool and harden to the shape of the model.  The wax model is removed from the mold, secured to a plate and placed in a flask. The flask is filled with plaster of Paris.  Once the plaster of Paris has hardened, the flask is placed in an oven to melt the wax model.  The melted wax is poured out and the mold is ready for use.

This classification also applies to manufacturing gold leaf and needles, medical needles (hypodermic only), sewing needles and pen points.
