(Ham et al., page 68.) C ratio in the past, or that this is "the technique's Achilles' heel" is incorrect.The whole validity of radiocarbon dating for the past 10,000 years---the time span of interest to biblical chronology---hangs only on the tree-ring chronologies which are used to calibrate it. .) This process does not involve any assumption about historic radiocarbon to stable carbon ratios because the radiocarbon concentration in the tree-ring samples would be affected in exactly the same way as the radiocarbon concentration in the specimen to be dated. To quote again from The Answers Book: Some recent, though controversial, research has raised the interesting suggestion that c (the speed of light) has decreased in historical times. If it is correct, then radioactive decay rates would automatically be affected, and would show artifically high ages.Activated carbon filters are relatively easy to install but require were used during the 18th and 19th century by the sugar industry for decolourising solutions (CECEN 2011).Activated carbon is a material prepared in such a way that it exhibits a high degree of porosity and an extended surface area.The characteristics of the carbon material (particle and pore size, surface area, surface chemistry, etc.) influence the efficiency of .

How do we know what the ratio was before then, though--say, thousands of years ago?

Unfortunately, a lot of misinformation about radiocarbon dating has been circulated by individuals who have neither training nor hands-on experience in this area.

We feel a responsibility to make sure readers of this site go away with factual, truthful information, and this requires a frank correcting of some prevalent misinformation.

However, human beings love to see factual precision, and we want to know how old something is.

Please remember that all dating methods, even those termed "absolute," are subject to margins of error. That is a very small amount of possible error range. Modern studies almost always use two or more methods to confirm dating work and to build confidence in the results obtained.
