While exact age dating of papers is not possible, the process is often able to exclude samples as being made in the time period of question. Walter Rantanen has developed a large database of paper with known ages.
Can you carbon date ink?
Yes, with certain limitations. We can determine the first date of commercial availability of the ink used to prepare any handwritten or handprinted material. The type of ink does not preclude this examination. As the ink ages these components decrease and thus the approximate age of the writing can be determined.
How do I make paper look old with ink?
Brew a cup of very strong black coffee, either instant or by normal brewing methods. Keep the coffee grounds separate for later use. Alternatively, use tea if you do not have coffee, but the results will not be as dramatic. Add vinegar, lemon juice or wine into the coffee to give the paper a yellowed effect.
How do you find erased pencil marks?
Try a strong torch, hold it in a shallow angle. If the books paper is not too heavy, try strong light from behind the page.Put some thin Japanese paper on the page and hatch gently with a soft pencil.Take e.g. light blue chalk and rub gently over the page.4 Nov 2019
