Quoted text begins.Is outdoor marble sculpture in Norway a really bad idea? I'm English and now
work in the Mediterranean so I've no experience of Norwegian winters and

sculpture idea for Oslo which would definitely work best in marble but not
if it's going to turn into a 3D jigsaw after a few years.
End of quote.
It will take more than a few years, depending on stone-quality.
In the Netherlands and Germany, marble is considered unsuitable for
outdoors. Untreated it will build a patina of withered chalk in the first
few years. Acid-rain and dust will probably create black patches on the
then raw surface. Frost-thaw cycles will wither the stone more deeply in
anything from 10-200 years.
Colored marble (e.g. from Portugal) will bleach in the sun.
On the one hand you could make withering part of your sculpture, on the
other hand you could try to protect it by polishing it and applying a new
layer of marble-wax every 6-12 months (keeps water out, reduces
frost-damage and makes the surface more resistent to dirt, acid rain and
organic growth).
Quoted text begins.I know Vigeland
worked a lot in granite but was this for practical reasons to do with the
climate or simply because he preferred the material?
End of quote.
Don't now, Norway has no marble but lots of granite.
Which properties of marble do you like for your project?
