← HistoryWhich risk increases for pietra dura inlay when significant diurnal temperature variation affects the Taj Mahal?
A)Differential thermal expansion occurs✓
B)Oxidation rate accelerates significantly
C)Material dissolution process accelerates
D)Microbial contamination increases rapidly
💡 Explanation
Delamination risk increases because differential thermal expansion occurs between the marble and the inlaid stones. The linear thermal expansion coefficients differ; therefore, internal stresses cause loss of adhesion rather than uniform change.
