Über Optimum Surfaces Taj Mahal 066
The reviewed evidence resolves Optimum Surfaces Taj Mahal 066 as a single ceramic product rather than a natural quartzite record. The official Taj Mahal product page fixes the visual identity, slab size, thicknesses, and finish set, while the official Optimum technical-characteristics PDF provides the porcelain performance baseline for water absorption, modulus of rupture, deep abrasion, thermal expansion, frost resistance, thermal shock resistance, chemical resistance, and stain resistance. That is sufficient to complete this row as a product-level ceramic canonical.
