Radiocarbon Dating

They have already done blind testing like that and it has demonstrated carbon 14 dating is accurate.

Not living, but yes they come from living things, cotton and wood for example.

oh wow, this was really interesting. Awesome to see the actual processes behind dating.

Tree rings are not the calibration basis for Radiocarbon dating - the dendrochronological calibration curves allow a fine adjustment of the data in regard to... see above

Always problems with a "bigger" comment... HELP *LOL*

C14 dating is an absolute method. The raw data out of the sample is the relation C14 / C12, and the C14 / C12 of air and the half life time of C14 are used to calculate the age.

The dendrochronological calibration curve then allows for a correction of the result in regard to the fact that the 14C/12C of air was not exactly constant over time

There are dozens of ways of dating rocks, and dozens of ways to date organic material. By dating a sample using several of these methods you know that the result is in the range of accuracy. Scientists also make predictions based on surrounding rocks/material and when several test results support their prediction you can be pretty certain the age is accurate. To be even more certain you take several samples.
