1. What is the primary purpose of annealing metal?
A) To harden it
B) To color it
C) To soften it for shaping
D) To clean it
Annealing involves heating metal and then cooling it to reduce
hardness and increase ductility, making it easier to work.
2. Which tool is commonly used to measure the thickness of sheet
metal?
A) Pliers
B) File
C) Micrometer
D) Chisel
A micrometer provides precise measurements of thin materials,
essential in jewelry making.
3. What is the main function of a flex shaft in a jeweler’s workshop?
A) Heating metals
B) Cutting stones
C) Rotary tool for polishing, drilling, and shaping
D) Measuring metals
, A flex shaft is a versatile rotary tool used for multiple bench
operations.
4. Which type of solder has the lowest melting point?
A) Hard solder
B) Medium solder
C) Easy solder
D) Silver solder
Easy solder melts at a lower temperature, allowing it to join
metals without disturbing previous solder joints.
5. What is the purpose of pickle solution in jewelry making?
A) Polishing metal
B) Hardening metal
C) Cleaning oxidation from heated metal
D) Strengthening solder joints
Pickle solution removes oxides and fire scale after soldering.
6. Which technique is used to create a hollow metal form?
A) Casting
B) Engraving
C) Repoussé
D) Filing
Repoussé involves shaping metal from the reverse side to create
a raised design.
7. What is the primary metal used in fine silver jewelry?
A) Nickel

A) Karat gold is synthetic
B) Gold plating is more durable
C) Karat gold is solid gold; plating is a thin layer over another
metal
D) No difference
Gold plating applies a thin layer of gold over a base metal,
whereas karat gold is solid throughout.
9. Which tool is used to shape rings evenly?

A bezel is a metal rim that encircles a gemstone to secure it in
place.
11. Which metal is commonly used for casting jewelry?
A) Aluminum
B) Steel
C) Gold, silver, or bronze
D) Lead
These metals have suitable melting points and malleability for
casting intricate designs.
