Which risk increases when the internal support weakens in Mughal pietra dura inlays?

💡 Explanation

Increased risk of inlay cracking and loss occurs with weakened internal support (adhesive layer delamination); this happens because stress concentrations cause the adhesive bond's cohesive failure, initiating surface cracks. Therefore blistering is not prevented with weak internal joins, rather than other surface degradation which operates by seperate mechanisms.
