The invention discloses an ultra-bright negative ion glazed brick. The negative ion concentration of the ultra-bright negative ion glazed brick is 5-10 times higher than that of a common glazed brick,and at the same time, a crystal structure reflects light to enable the glazed brick more bright. The glazed brick comprises a bottom layer green body, a sound-insulation insulating layer, a top layergreen body, a base glaze layer, a functional layer and an overglaze layer; the bottom green body and the top green body comprise stone powders, sand, ultra-fine negative ion powders, diatom mud, mud,waste residues and broken mud of ceramic and water; the sound-insulation insulating layer includes a polyamide mesh, asbestos fibers and gypsum powders; the base glaze layer includes potassium sodiumfeldspar, quartz, alumina, washed soil, burnt talc, zirconium silicate and ultra-fine negative ion crystals; the functional layer includes ultra-fine negative ion crystals, activated carbon, diatom mud and glass beads; and the overglaze layer includes potassium sodium feldspar, barium carbonate, dolomite, zinc oxide, burnt talc, burnt soil, washed soil, corundum, nanometer titanium dioxide, and ultra-fine negative ion crystals.
