TL testing is the best scientific test available to determine the "Zero"
point or, date of manufacture of:
To determine the Zero point it is necessary to discover the last
date of kiln firing.When a small sample is taken from an object and
heated in the lab, a faint blue light is emitted. This
Thermoluminescence, or TL for short, can be detected and measured
using special light sensitive equipment. The measurements are used
to calculate the date the object was either manufactured or last
fired. The brighter the light, the older the object.TL testing is
widely used by museums, dealers, collectors and auction houses as a
means of verifying the dating of ancient artifacts.
