[Rooted Arborial]

Marble is a relatively soft and porous stone which - through time and weather and acidity in the weather - can warp and will definitely erode. I can see how it

might last longer and be more stable where the weather is milder. I'm wondering if there is a level of freezing and at what latitude it might be more

likely to last, but i really think it is generally foolish to use it on any exterior.

Even indoors, I've seen stairs which were marble and looked so worn down that I definitely held on to the railing.

Using it on the facade of building has always reminded me of 19th Century gravestones which can no longer be read.
