The main surface of a quartz component is divided by an offset into a first region having a larger height around an inner perimeter and a second region adjacent to the outer perimeter of the first region. Repeated restoration of a damaged component by forming a bulge on the first region and machining the bulge to make a flat surface while maintaining the offset enables long term use of the component.
