Traces of Schreger
The Traces of Schreger, seen as a result of tubular construction of the dentine, seem as random, brief and dashed, and generally barely curved, strains in a micrograph. The Traces of Schreger differ significantly from species to species. They are usually parallel to the lengthy axis of the tusk or tooth. This can be of assist in differentiating between the ivory of the Asian elephant (Elephas maximus) and the African elephant (Loxodonta africana). Within the latter, the Traces of Schreger are extra persistently parallel than within the former. The width of the Traces of Schreger, in addition to their form and course, is nearly invariable inside a species.
A further characteristic is offered by the Incremental Traces of Owen. These are generally seen in addition to the Traces of Schreger and are concentric with the annulations of the tusk or tooth. Their presence is, nevertheless, way more variable than that of the Traces of Schreger. The Incremental Traces of Owen are barely wavy and brown-stained.
| Asian elephant (Elephas maximus) | African elephant (Loxodonta africana) | |
|---|---|---|
| Traces of Schreger | Not at all times parallel to the lengthy axis of the tusk | Principally parallel to the lengthy axis of the tusk |
| Incremental Traces of Owen | Not at all times seen | Not noticed |
The Presence of Cracks or Flaws
Real ivory reveals a novel floor texture with superb parallel striations or strains, making a attribute “hairline” sample. Conversely, faux ivory could have a easy, synthetic look and lack these delicate striations.
Moreover, actual ivory tends to develop hairline cracks or flaws over time attributable to pure growing old and temperature fluctuations. These cracks, also known as “crazing,” are sometimes shallow, parallel, and per the pure grain of the ivory.
In distinction, faux ivory could have extra pronounced cracks or flaws which can be irregular in form and seem superficial, slightly than ingrained throughout the materials. These flaws could point out manufacturing defects or using low-quality supplies.
| Issue | Real Ivory | Pretend Ivory |
|---|---|---|
| Floor Texture | Positive parallel striations (“hairline” sample) | Clean, synthetic look |
| Cracks and Flaws | Hairline cracks or crazing; shallow, parallel, per grain | Pronounced, irregular cracks; superficial, indicative of producing defects |
The Oxidation Check
