The Age of the Earth - Radiocarbom Dating as a Current Scientific Clock: Jonathan Ring
Dating of mortar has been a challenge since the early days of the radiocarbon dating method. The idea is to date only the carbon fixed in mortar at the time of binding i. Also, non-binder carbon can be incorporated into mortar sample 1 due to precipitation of secondary carbonates from environment, 2 in case of fire accidents, it is replaced with the carbon from the atmosphere at the time of accident, or 3 if the mortar is too alkaline, it still incorporates carbon from the atmosphere. Therefore, an effort is placed into developing of a method that can isolate strictly the binder carbon, with the help of the accelerator mass spectrometry AMS measurement technique enabling analyses of various phases of mortar. However, no reliable procedure has yet been established for each mortar type Hajdas et al. The Aqueduct is one of the landmarks of Skopje, a monumental building more than m long.

Archeologists use various methods to date objects. And if the artifact is organic, like wood or bone, researchers can turn to a method called radiocarbon dating. Radiocarbon dating, or simply carbon dating, is a technique that uses the decay of carbon 14 to estimate the age of organic materials. This method works effectively up to about 58, to 62, years. Since its introduction it has been used to date many well-known items, including samples of the Dead Sea Scrolls, enough Egyptian artifacts to supply a chronology of Dynastic Egypt, and Otzi the iceman.
