Which outcome occurred due to decreased timber availability in late Byzantine mosaic production?

💡 Explanation

Timber scarcity shifted mosaic support to gypsum, which suffers increased hygroscopic expansion; this in turn leads to movement in the tesserae because gypsum absorbs moisture therefore inducing instability in the mosaic surface, rather than improvements in gilding.
