The latest computer technology supports and completes analysis.X-Ray Fluorescence / XRF spectroscopy is widely used for qualitative and quantitative elemental analysis of archaeological samples.Thermoluminescence can test fired clay such as pottery, earthenware and terracotta, as well as porcelain, stoneware and the casting cores of bronzes.Artemis Testing Lab can test pieces from any culture, as long as they have been fired to above 500°C and the clay contains a sufficient quantity of TL minerals (quartz and/or feldspars), as well as radioactive inclusions (normally uranium, thorium and a radioactive form of potassium). Generally speaking, when a sample is drilled and there is no information available about the burial environment, one may expect /- 25% uncertainty, and this is more than adequate for authentication where the question is whether the piece was fired in antiquity or recently.As pottery ages, it absorbs radiation from its environment.
Quantity discounts available for dealers, collectors and institutions. Digital and/or film X-Ray images will show what’s ancient… as well as true condition of any pottery or metal object. Rate does not include shipping cost of item to/from the lab.XRF can be used to test a wide range of materials from ceramics to metals and glass.XRF testing provides a good, uniform detection level across a large portion of the Periodic Table and is applicable to a wide range of concentrations, from 100% down to a few parts per million (ppm).Artemis Testing Lab is the only US-based company that offers comprehensive authentication services using Thermoluminescence (TL), X-Ray fluorescence (XRF) and traditional X-Ray testing methods.Headed by Serge Fayeulle, Ph D, Artemis Testing Lab provides expert testing / analysis to distinguish between genuine and fake ancient / ethnographic art.
