We cannot, however, through this technique, determine the specific or even approximate date of preparation. Other techniques can determine the approximate date of preparation of handwritten entries. Additionally, it is possible to measure the quantity of several semi- volatile components that are present in ink. As the ink ages these components decrease and thus the approximate age of the writing can be determined. Not to the same degree as handwritten documents or signatures. It is not possible to determine commercial availability of these materials with the same degree of certainty as was possible with writing ink.
