Which risk increases at a Byzantine mosaic workshop when ambient humidity spikes?

💡 Explanation

High humidity weakens the animal-hide glue ( κερόκολλα ) used to adhere tesserae when building large Byzantine mosaics because moisture reduces intramolecular cohesion. Therefore, tesserae risk sliding before setting, rather than remaining fixed; thermal activity or oxidation are generally slower.
