Limits to relative dating are that it cannot provide an accurate year or a specific date of use. Thermoluminescence can replace radiocarbon dating to date events that occurred more than 50 years ago; it is used mainly for dating stone fireplaces, ceramics and fire remains. The greatest problem with dating an artefact from an archaeology site is that nearly every absolute dating process requires the destruction of at least a piece of the object in conducting the analysis. This is admitted because of the simple reason that some botanical species, whether extinct or not, are well known as belonging to a determined position in the scale of time. MAL - May No provenance and its a fake! This method provides very accurate dating, sometimes to the nearest year.
Crystalline minerals when subjected to intense heat will burn with differing colours of flame.
