It is in knowing what made past cultures cease to exist that could provide the key in making sure that history does not repeat itself.Over the years, archaeology has uncovered information about past cultures that would have been left unknown had it not been with the help of such technologies as radiocarbon dating, dendrochronology, archaeomagnetic dating, fluoride dating, luminescence dating, and obsidian hydration analysis, among others.Aluminum containers with screw caps are safe, but it is still best to consult the radiocarbon laboratory for the best containers of carbon dating samples.
This information is then related to true historical dates.
Some samples, like wood, already ceased interacting with the biosphere and have an apparent age at death and linking them to the age of the deposits around the sample would not be wholly accurate.
There are also cases when the association between the sample and the deposit is not apparent or easily understood.
Labels attached to the packaging materials must not fade or rub off easily.
Glass containers can be used when storing radiocarbon dating samples, but they are susceptible to breakage and can be impractical when dealing with large samples.
