Worldwide oldest private Laboratory for TL testing authenticity Analyses since 1979 .
We have tested more than 120,000 samples of ceramic and bronze objects (with approximately 1,200.000 individual data) This wealth of experience in the application of a so-called absolute Tl measurement method yielded numerous saturations of authentically fired samples and newly fired to the tested objects .
- Ceramics, fired clay
- Metal objects with residual iron cores
- Art objects
- Stoves, tile, masonry
We offer you
- TL-analyzes / reports
- Porcelain reports (incl. ICP / MS with authentic samples)
- TL test certificate with ICP / MS analysis
- Ceramic structural test
- CT scan (computed tomography)
- AMS 14 C
Help and Security for your objects
When analyzing your artefact only small quantities are needed for sampling,so that the objects are not unnecessarily damaged.The sample quantities are minimal (50-200 mg).The TL-analysis provides some information about the last time of heating to the samples!
Part-statements in the report as an example:
Analysis results of the individual/s sample/s 1 8 0 0 years (+/- 20%)
The powder sampling was carried out by myself at the following locations: A.Sample : Buttocks B: Shoulder C : Head chin
Since 1979 TL-analysis of ceramics from such differnt areas as, for example, Chinese, Antique, African or Pre-Columbien culture underlines great experience. Latest computer technology supports and completes analysis. Thus defination of age is possible with +/- 15-35% exactitude. This is more than sufficient to identify modern imitations.
