Which consequence occurs when insufficiently seasoned marble receiving pietra dura experiences significant variations in humidity?

💡 Explanation

Differential thermal expansion cracks the marble because the varying moisture content causes uneven expansion/contraction around the dura inlay; therefore, cracking occurs, rather than discoloration or other surface phenomena unrelated to internal stresses.
