...are some conservationists cracked?
Some certainly are, but conservators are generally very well balanced ;-)Good example though Nigel. Assuming that the same type of stone has been used for the conservation it will mature naturally within a few years, and presumably not look dissimilar to the original. Had it been artificially aged it might have ended up looking darker than the original. Another golden rule in conservation is that any necessary additions (as in stonework) should be lighter not darker than the original).
