Ballpoint ink dating heating
Evaporation of ink solvents begins in the first few minutes during which time there is a rapid and significant loss.This method can be useful only when the inks are still drying (up to six years but more likely one to two years) as solubility changes cease once ink has completely dried..action_button.action_button:active.action_button:hover.action_button:focus.action_button:hover.action_button:focus .count.action_button:hover .count.action_button:focus .count:before.action_button:hover .count:before.u-margin-left--sm.u-flex.u-flex-auto.u-flex-none.bullet.

Analysis of the ink deposited on a document can then assist in determining a date after which the writing must have been made, that is the date will be on or after the date of manufacture of the ink containing a tag.Whether such tags occur in ballpoint pens available generally in Australia is not known.

After so many years i thought id be able to let you go, but i told you so.
Additionally, as resins in inks harden, which begins on deposit, their solubility diminishes and importantly they trap colourants.
This leads to the position that the longer the ink has been deposited the more difficult it is to extract colourants.
However, this tool is useful only for between eight months and two years.
This leads to the position that to be able to determine when writing was made it is necessary to know whether the ink is still ageing and how it ages; this can be achieved by heating.
