Advanced Jewelry Repair & Design Techniques Flashcards

What is the purpose of a pickle solution in a jewelry workshop?

Answer: To clean metal by removing flux residue and oxides after soldering

Pickle is a mild acid solution (often sodium bisulfate) used to dissolve flux residue and surface oxides from metal after soldering, leaving a clean surface.

In CAD/CAM jewelry design, what does the acronym CAM stand for?

Answer: Computer-Aided Manufacturing

CAM (Computer-Aided Manufacturing) refers to using software and machines like 3D printers or CNC mills to produce a physical model from a digital design file.

When a customer requests a ring to be converted from a four-prong to a six-prong setting, the jeweler must first consider:

Answer: Whether the existing head can be modified or if a new head must be fabricated

Converting prong count often requires replacing the head (the prong assembly) because adding prongs to an existing head may not be structurally feasible.

What distinguishes a 'flush' or 'gypsy' setting from other setting styles?

Answer: The stone is set level with the metal surface with no protruding metal above it

In a flush (gypsy) setting, the stone is set into a drilled hole so its table sits level with the surrounding metal surface, with no prongs or bezel raised above it.

What is 'mokume-gane' in jewelry design?

Answer: A Japanese technique of laminating and manipulating mixed metal layers to create wood-grain patterns

Mokume-gane is a traditional Japanese metalworking technique that bonds alternating layers of different metals and then manipulates them to reveal swirling wood-grain-like patterns.

A customer's antique ring has worn-through knife-edge shanks. The best repair approach is to:

Answer: Cut out the worn section and solder in a new shank section of appropriate metal

Removing the deteriorated section and inserting a new shank segment provides a structurally sound repair that restores the ring's integrity.

When using a flex shaft to pre-polish a casting before final polishing, which abrasive sequence is correct?

Answer: Start with coarse abrasive to remove casting skin, then progress to finer grits

Proper surface preparation moves from coarse to fine abrasives, progressively removing deeper scratches until the surface is ready for polishing compound.
