Area of competence
- Reliable evaluation of the authenticity of baked clay objects requires, besides complex
technical equipment, wide expert knowledge.
- 30 years of TL-analysis of ceramics from such differnt areas as, for example, Chinese,
Antique, African or Pre-Columbien culture underlines great experience.
- The tests for authencity are performed according to the thermoluminecence-procedure (TL).
Latest computer technology supports and completes analysis. Thus defination of age is
possible with +/- 20-35% exactitude. This is more than sufficient to identify modern
imitations.
