Difficulty: MediumSequential Steps and Chronology

Read the following instructions for restoring a historic stained glass window:

To restore a historic stained glass window, conservators must adhere to a precise sequence of preservation steps. First, they create a rubbing of the window using charcoal and heavy paper to document the exact layout of the lead cames. Immediately after completing this documentation, the window is carefully dismantled, and the individual glass fragments are cleaned. Prior to re-leading the glass, any fractured pieces must be stabilized using specialized epoxy resin. Once all pieces are repaired and reassembled within new lead cames, the joints are soldered. Finally, a waterproofing linseed-oil cement is applied to seal the gaps; however, the window must not be reinstalled in its frame until this cement has cured for at least three weeks.

Based on the instructions provided, which action must be performed immediately prior to assembling the glass pieces with new lead cames?

  1. A
    Creating a detailed charcoal rubbing of the original window layout
  2. Stabilizing any fractured glass pieces with epoxy resinAnswer
  3. C
    Soldering the joints of the newly assembled lead cames
  4. D
    Reinstalling the restored window into its original frame

Answer

Stabilizing any fractured glass pieces with epoxy resin
Stabilizing fractured glass pieces with epoxy resin is correct because the instructions explicitly state that this step must be performed 'prior to re-leading' (assembling the glass with new lead cames). Therefore, this is the action required immediately before the reassembled glass is put into the lead cames.

Step-by-Step Solution

1
Locate the portion of the text discussing the assembly of the glass pieces with new lead cames.
The text refers to this process as 're-leading the glass' and notes that it follows the cleaning phase.
Establishing a chronological anchor point in the instructions is necessary to determine the sequence.
2
Identify the temporal marker associated with the re-leading process.
The marker 'prior to' is used in the sentence: 'Prior to re-leading the glass, any fractured pieces must be stabilized using specialized epoxy resin.'
Temporal markers indicate the relative ordering of events.
3
Confirm the immediate predecessor step by ruling out other options.
Since stabilization happens directly 'prior to' re-leading, it is the step that must be completed immediately before the assembly.
Ensuring no other intermediate steps are mentioned in the text confirms the correct sequence.
