I am not sure, but it seems to me that the top of the object was burnt by deposits of acid drops.
the calcification of an old object keeps a certain brighter one has a visual impression of hardness
when it is not the case that the calcification is too important it gives a somewhat velvety aspect like a peach skin linked to the formation of crystals.
all it is obviously my opinion which can be wrong.
