Why doesn’t tile last forever? I’ve heard about the tile in European cathedrals and Oriental palaces that has been there for centuries. Why is Ragno warranted for one year?

A tile’s ability to withstand wear is determined by many factors, i.e. glaze composition, surface texture, traffic levels, maintenance procedures, etc. Ragno’s standard limited warranty addresses the issue of a tile’s conformance to industry standards regulating First Choice products. Any variation from those standards would be evident within a one-year period.

You can bet that the tile in those ancient installations looks much different now than it did when it was installed. More than likely, the edges are chipped; the surface is scratched and worn (in many cases through to the body); there are impact chips and structural cracks - all of which may seem acceptable in an historic site but less so on your kitchen floor!
