Practice question · Sort into groups
Sort each material by how it behaves in contact with a silver print.
Groups: Safe for long-term contact · Acceptable for short-term handling · Actively harmful
- Rubber print band
- Self-adhesive album
- PAT-tested board/paper
- Untested clean box
- Kraft paper interleaf
- Polyester sleeve
Hints
- One test exists precisely because appearance tells you nothing.
- Rubber and many adhesives release sulfur compounds.
Show the answer
Safe for long-term contact: PAT-tested board/paper, Polyester sleeve
Acceptable for short-term handling: Untested clean box, Kraft paper interleaf
Actively harmful: Rubber print band, Self-adhesive album
Why
The middle column is where honesty lives. Untested materials are not proven harmful, they are simply unknown, and for a few weeks that is a tolerable risk. The two harmful items are harmful for the same reason, sulfur, and both are the sort of thing found in domestic albums everywhere.
