[Nhcoll-l] vanishing ink

[Erik Åhlander]

Dear Thomas,

Usually it doesn't help much. Sun light from different sides might help as well as a stereo microscope. Good light is important. Most important is experience and fantasy. It is possible to learn to read also labels in very bad state. That is one of the reason never to through away a label regardless of condition. Somebody else might find out more information in the future.

Dear colleagues

We are making an inventory of a fruit collection (jars from 1900-1905) which external labels have turned yellow (in fact brown) ; some are illegible.
Is there a way to reveal the faded ink ?  (chimical or light based)

Thanks a lot
