Reading Onyx Slab Resin and Fiberglass Backing before Cutting

he reverse of an onyx slab can be as important as the glowing face. Resin may stabilize fissures or fill openings, while fiberglass mesh can assist handling of fragile material. Both can become visible under transmitted light and can affect bonding, edge construction, cutting, repairs, and the appearance of joints. This MQ STONE review maps treatment before fabrication, uses representative adhesive and light-box trials, and keeps the selected slab, support system, and finished edge inside one complete physical approval record.
