Jewelry Design Jewelry Design MCQ 3 â Questions and Answers
Question 1: What is the primary purpose of borax flux when soldering jewelry?
- To prevent oxidation and help solder flow (Correct answer)
- To increase the melting point of solder
- To harden the metal after cooling
- To add color to the solder joint
Correct answer: To prevent oxidation and help solder flow
Borax flux prevents oxidation of metal surfaces during heating and lowers surface tension so solder flows smoothly into the joint.
Question 2: In the lost-wax casting process, what immediately replaces the wax model inside the investment mold?
- Molten metal poured or injected into the cavity (Correct answer)
- Epoxy resin for a prototype
- Plaster of Paris for a duplicate
- Ceramic slip for a test cast
Correct answer: Molten metal poured or injected into the cavity
After the wax is burned out (lost) from the investment, molten metal is forced or poured into the resulting cavity to produce the final metal piece.
Question 3: Which of the following best describes 'chasing' in metalwork?
- Refining and detailing a repoussé design from the front using punches (Correct answer)
- Cutting metal with a jeweler's saw
- Applying chemical patina to a finished piece
- Filing the edges of a bezel to fit a stone
Correct answer: Refining and detailing a repoussé design from the front using punches
Chasing is the process of working on the front side of a repoussé piece with punches and a chasing hammer to define and refine surface details.
Question 4: What is 'karat' measuring when applied to gold jewelry?
- The purity of gold expressed as parts per 24 (Correct answer)
- The weight of the gold in the piece
- The hardness of the gold alloy
- The color grade of the gold
Correct answer: The purity of gold expressed as parts per 24
Karat measures gold purity on a scale of 24, so 18-karat gold is 18 parts gold out of 24 parts total, or 75% pure gold.
Question 5: Which type of enamel technique involves filling separate compartments created by thin metal wires with colored glass paste?
- Champlevé
- Cloisonné (Correct answer)
- Plique-Ă -jour
- Basse-taille
Correct answer: Cloisonné
Cloisonné uses thin metal wires (cloisons) soldered onto a base to form compartments that are then filled with colored enamel and fired.
Question 6: What distinguishes 'mokume-gane' from standard alloyed metal?
- It is a laminated billet of different metals diffusion-bonded and manipulated to reveal patterned layers (Correct answer)
- It is a single-element metal hardened by cold working
- It is an electroplated coating applied over a base metal
- It is a hollow form created by hydraulic forming
Correct answer: It is a laminated billet of different metals diffusion-bonded and manipulated to reveal patterned layers
Mokume-gane is a Japanese technique where multiple metal sheets are diffusion-bonded into a billet, then carved, twisted, or rolled to expose wood-grain-like patterns.
Question 7: When selecting a file for finishing a silver ring shank, which file cut would remove material fastest?
- Bastard cut (Correct answer)
- Second cut
- Smooth cut
- Needle cut
Correct answer: Bastard cut
A bastard cut file has the coarsest teeth among standard file grades, removing material most aggressivelyâideal for initial shaping before finer finishing.
