Which degradation accelerates when mosaic tesserae experience differential thermal expansion?

💡 Explanation

Mechanical bond weakening occurs because fluctuating temperatures cause differential thermal expansion between the mosaic tiles and the underlying mortar. This stress creates tension leading to eventual cracking (debonding) therefore, weaker bond rather than biofouling which is biological.
