Controlled values on this axis
This table scrolls sideways on narrow screens.
| Value | Status |
|---|---|
| Natural identity; treatment status unknown | A placeholder value rather than a real class (unknown / not applicable / mixed), so it has no page of its own; on entry pages the value is shown as plain text without a link. |
| Treated: dyed | Fewer than three member entries; folded into the axis index page instead of a standalone page, to avoid thin content. |
| Man-made glass | Has its own page |
| Synthetic product | Has its own page |
| Assembled / composite product | Has its own page |
| Imitation; record actual material | Has its own page |
| Reconstructed / pressed material | No glossary entries carry this value, so no standalone page is built; the term remains listed in the controlled-vocabulary table. |
| Artificial material with no natural counterpart | Has its own page |
| Actual material to be verified | Has its own page |
| Cultured formation; treatments recorded separately | Has its own page |
