Onyx slab resin and fiberglass backing must therefore be mapped on the exact slab and tested inside the intended assembly.

Why are some onyx slabs backed with fiberglass mesh?<\/span><\/h4>\n<p><span style=\"font-family: arial, helvetica, sans-serif;\">Mesh and resin may assist handling or stabilize fragile features during processing. The exact purpose and system vary. Record the treatment and assess how it affects transmission, bonding, edges, cutouts, support, and the final assembly.<\/span><\/p>\n<h4><span style=\"font-family: arial, helvetica, sans-serif;\">2. Can fiberglass backing be seen through backlit onyx?<\/span><\/h4>\n<p><span style=\"font-family: arial, helvetica, sans-serif;\">It can become visible through especially translucent zones or an unsuitable light-box build-up. Test the exact slab, mesh, resin, adhesive, diffuser, source distance, supports, and viewing position.<\/span><\/p>\n<h4><span style=\"font-family: arial, helvetica, sans-serif;\">3. Should resin-treated onyx be rejected?<\/span><\/h4>\n<p><span style=\"font-family: arial, helvetica, sans-serif;\">Not automatically. Treatment is common in fragile decorative stone, but it must be disclosed and mapped.
