A method for manufacturing a semi-transparent ceramic sheet having a light transmittance between 10% and 45%, comprising the steps of: preparing a semi-transparent green body; applying a decoloration glaze on the semi-transparent green body to give a decoloration glaze layer located on the upper surface of the semi-transparent green body; the formula of the decoloration glaze is: 0 to 9 parts of ultra-white kaolin, 8 to 15 parts of C30 soil, 15 to 35 parts of quartz, 2 to 20 parts of fused silica, 8 to 20 parts of calcined talc powder, 20 to 35 parts of potassium feldspar powder, 3 to 7 parts of bentonite, and 0.5 to 5 parts of nano zinc oxide; wherein C30 soil is: 5.62 parts of IL (ignition loss), 67.28 parts of SiO 2 , 17.83 parts of Al 2 O 3 , 0.45 parts of Fe 2 O 3 , 0.01 parts of TiO 2 , 0.13 parts of CaO, 0.55 parts of MgO, 1.34 parts of K 2 O, and 0.36 parts of Na 2 O; wherein the primary particle size of the nano zinc oxide is less than 800 nm; and wherein all parts are by weight; applying a first inkjet infiltrating ink on the decoloration glaze layer to provide an inner inkjet pattern layer infiltrating into the semi-transparent green body from an upper surface of the semi-transparent green body, wherein the first inkjet infiltrating ink is an inkjet infiltrating brown ink containing iron oxide and the decoloration glaze is capable of decoloring the first inkjet infiltrating ink in the decoloration glaze layer; and after the first inkjet infiltrating ink having completely infiltrated into the decoloration glaze, applying a second inkjet non-infiltrating ink on the decoloration glaze to give a surface pattern layer, and then sintering to obtain the semi-transparent ceramic sheet. preparing a semi-transparent green body; applying a decoloration glaze on the semi-transparent green body to give a decoloration glaze layer located on the upper surface of the semi-transparent green body; the formula of the decoloration glaze is: 0 to 9 parts of ultra-white kaolin, 8 to 15 parts of C30 soil, 15 to 35 parts of quartz, 2 to 20 parts of fused silica, 8 to 20 parts of calcined talc powder, 20 to 35 parts of potassium feldspar powder, 3 to 7 parts of bentonite, and 0.5 to 5 parts of nano zinc oxide; wherein C30 soil is: 5.62 parts of IL (ignition loss), 67.28 parts of SiO 2 , 17.83 parts of Al 2 O 3 , 0.45 parts of Fe 2 O 3 , 0.01 parts of TiO 2 , 0.13 parts of CaO, 0.55 parts of MgO, 1.34 parts of K 2 O, and 0.36 parts of Na 2 O; wherein the primary particle size of the nano zinc oxide is less than 800 nm; and wherein all parts are by weight; applying a first inkjet infiltrating ink on the decoloration glaze layer to provide an inner inkjet pattern layer infiltrating into the semi-transparent green body from an upper surface of the semi-transparent green body, wherein the first inkjet infiltrating ink is an inkjet infiltrating brown ink containing iron oxide and the decoloration glaze is capable of decoloring the first inkjet infiltrating ink in the decoloration glaze layer; and after the first inkjet infiltrating ink having completely infiltrated into the decoloration glaze, applying a second inkjet non-infiltrating ink on the decoloration glaze to give a surface pattern layer, and then sintering to obtain the semi-transparent ceramic sheet. <EOS>
