Hi. I have two somewhat old pieces which are made of leather. They both display different characteristics, but I'm at a loss for both.
If anybody has suggestions or even technical/proper descriptions so I can read up on what I'm seeing I'd be appreciative.
Thanks.
- A WWI era helmet for which the thin liner has become brittle and tears easily along clean straight lines in areas of stress.
- A mid 19th century piece of thicker leather whose characteristics I would almost descibe as dry rot? It's feels sort of spongy and if I wrap my hands around it firmly and pull them away little bits of the leather no bigger than a pinhead come away with my hand.
If anybody has suggestions or even technical/proper descriptions so I can read up on what I'm seeing I'd be appreciative.
Thanks.
