Description
A stone deterioration pattern caused by environmental temperature fluctuations that is commonly found on marble. Sugaring occurs when thermal cycles create micro-cracks at the boundaries between calcite grains, resulting in granular disintegration of the stone matrix. The stone surface exhibits a sugar-like powder of isolated calcite grains.
