CBJ Practice and Application 5

Question 1

When preparing a ring shank for sizing, a jeweler notices prior solder joints along the shank. The safest approach is to:

Accepted Answer

Identify all existing solder and plan cuts and new soldering to avoid re-flowing them

Answer

Mapping existing joints allows the jeweler to control heat and avoid accidentally opening old seams during the new soldering operation.

Question 2

A jeweler is setting a row of channel-set princess-cut stones and notices one stone is slightly smaller than the rest. The correct response is to:

Accepted Answer

Replace the undersized stone with one that matches the specified calibrated size

Answer

Consistent calibrated stones are required for channel settings to ensure uniform tension and appearance across the row.

Question 3

What is the purpose of using binding wire when soldering multiple components simultaneously?

Accepted Answer

To hold parts in precise alignment so they do not shift when solder flows

Answer

Binding wire keeps components in correct position throughout the heating cycle so solder flows into properly aligned joints.

Question 4

A customer's emerald ring needs re-tipping on one prong. Because emerald is a heat-sensitive stone, the jeweler should:

Accepted Answer

Remove the stone before soldering and reset it after the repair cools

Answer

Removing heat-sensitive stones before any soldering is the safest protocol and eliminates all risk of thermal shock damage.

Question 5

When using a rolling mill to reduce metal sheet thickness, the correct procedure for each pass is to:

Accepted Answer

Reduce roller gap by a small, consistent increment per pass and anneal as needed

Answer

Gradual reductions in small increments prevent stress cracking and extend the life of both the metal and the rolling mill.
