Leathered Quartzite Slabs: Where Texture Helps and Where It Does Not

Leathering can turn quartzite from a reflective image into a surface with measurable relief. Hard crystalline bands may remain high while other mineral zones recess, so one small offcut cannot represent the whole slab. Approval needs samples from the calm field, strong vein, mixed zone, and any treated feature that enters the cut pieces. The proposed edge must be made at full thickness, then checked under grazing light and with the intended cleaning method. That record distinguishes deliberate texture from an uneven finishing process across tables, counters, consoles, or wall panels.
