Ageing properties of chrome-tan

I made it sound very scientific....

No,I don't have any specifically. But I was thinking of things like cutting off a little swatch of leather and then rubbing it against a pair of older blue jeans. Or rubbing a very slightly damp cloth with a little dirt on it against the leather. Then leave it in the sun for a few days and see how it looks. Do the same thing to a piece that has been protected with acrylic resolene and compare the two.

At the end of the day, I think one can confidently say that white leather, crome tanned or not, will not age particularly well. The question becomes then, what can one do to make it look its best for as long as possible.
