Well, earthy would be lava/magma, because sedimentary rocks are only transformed into metamorphic rocks through heat and pressure. If you mean by chemical weathering...well there are a lot of chemicals that can change th composition of a rock! Oxygen, for example, oxidizes materials when combined with other matreials. Ex: oxygen + iron = Rust -->ferric oxide.

Lava is typically 700-1250 C. Nichrome resistance wire sustains 1100 C in air and melts at 1400 C. An arc furance does 1800-2000 C, an induction furnace will do 3000 C. A propane-oxygen torch does 2200 C; oxy-acetylene 2700 C, hydrogen-oxygen 3200 C.
Radioactive decay over time plus enough thermal insulation will do it.

I hope you mean earthly and not earthy.
One means of the earth and the other means soil-like.
No amount of any kind of soil will metamorphize rock, but materials like molten lava will. Glaciers will compress rock but not change the composition. Other forces are compression of rock upon rock, earthquakes and slips, and so on. Also chemicals in the air will "corrode" rocks like limestone and marble, which is a threat to the sculpture standing outdoors.

Lava or magma could do this, forming metamorphic rock. Check the page below for more info on how metamorphic rocks are formed.

Lava? I'm not certain what answer you're looking for.
