← HistoryWhich outcome occurs when excessive grinding during pietra dura inlay weakens the tesserae?
A)Adhesive bond strength decreases notably✓
B)Dimensional stability exhibits an increase
C)Refractive index rises unexpectedly high
D)Thermal conductivity improves substantially
💡 Explanation
Reduced tesserae thickness causes decreased surface area for adhesive bonding because careful fitting, rather than maximizing volume matters; therefore, the adhesive bond weakens rather than strengthen, because the attachment relies on sufficient tesserae adherence.
