Getting Your Item Tested
The analysis of antiquities by XRF is fast, efficient and safe. The testing process is entirely non-destructive and does not impair the surface of the object. Your artefacts (for example, coins, jewellery, ceramics and other antiquities) requiring authentication and certification should be made available to one of our specialist teams.
Antiquity testing and dating and ancient artefact validation are only two of the many applications of XRF technology – for environmental studies and verification of recycled materials, contact our specialists for a site visit appointment. Contact Oxford Labs for details.
What we need to know
- Where the object is – so that we can recommend our nearest agent or arrange a site visit.
- The type and quantity of objects you require to be tested – e.g. bronze Medieval statuette, gold Roman ring, ten silver Viking coins, etc.
What you should know
- XRF is a totally non-destructive method: delicate and fragile artefacts can be analyzed at atmospheric pressure without risk of damage.
- Certification will include your results displayed in a table of elements and a spectrograph image showing the composition.
- Certification will include a statement advising whether the analysis is consistent with our database of known authentic results for similar objects.
- Our certificates are held in very high regard worldwide and can add greatly to the value of a piece.
How to get your item tested
- Arrange for your item to be sent or brought to one of our agents by either telephoning us or using the contact page.
- For collections it may be possible for us to test your pieces on site, in situ.
