What this means for you
The chemical-hazard rating is what drives the score down. Engineered 'quartz' stone is typically over 90% crystalline silica, against 40–50% for granite. Dry-cutting it releases respirable silica that permanently scars the lungs; hundreds of silicosis cases have been counted among fabricators. Householders are barely exposed unless a slab is dry-cut indoors.
