Its disadvantages are: because the initial melting point is too high, it is easy to crystallize at 1060°C, resulting in dull glaze, and it is impossible to make the decals sink into the glaze to form in-glaze decals, and the content of zinc oxide is too high, so that some pigments cannot be glazed. hair color

Embodiment 1
[0037] The manufacture method of described transparent glaze is as follows:
[0038] Cut according to the proportion of each component → ball mill for 28 hours → pass through 400 mesh and the residue is 0.75% → take out the mill and put it in a glaze bucket for standby → adjust the specific gravity to 1.4 → glaze → firing at 1250°C → finished product.
[0039] Components of the transparent glaze and its mass percentage are: Na 2 O: 2%; K 2 O: 1.5%; Al 2 o 3 : 11%; CaO: 4%; MgO: 3%; ZnO: 8%; ZrO 2 : 3%; high temperature frit: 10%; loss on ignition: 4%; SiO 2 was 53.5%.
[0040] The melting temperature for making the high-temperature frit is 1350°C.
Embodiment 2
[0042] The manufacture method of described transparent glaze is as follows:
[0043] Cut according to the proportion of each component → ball mill for 32 hours → pass through 400 mesh and the residue is 0.6% → take out the mill and put it in a glaze bucket for standby → adjust the specific gravity to 1.35 → glaze → firing at 1240°C → finished product.
[0044] Components of the transparent glaze and its mass percentage are: Na 2 O: 1.3%; K 2 O: 1.8%; Al 2 o 3 : 10%; CaO: 7%; MgO: 1%; ZnO: 5%; high temperature frit: 25%; loss on ignition: 1%; SiO 2 was 47.9%.
[0045] The melting temperature for making the high-temperature frit is 1400°C.
Embodiment 3
[0047] The manufacture method of described transparent glaze is as follows:
[0048] Cut according to the proportion of each component → ball mill for 30 hours → pass through 400 mesh and the residue is 0.8% → take out the mill and put it in a glaze bucket for standby → adjust the specific gravity to 1.35 → glaze → firing at 1260°C → finished product.
[0049] Components of the transparent glaze and its mass percentage are: Na 2 O: 1%; K 2 O: 2.5%; Al 2 o 3 : 9%; CaO: 5%; MgO: 4%; ZrO 2 : 1%; high temperature frit: 30%; loss on ignition: 5%; SiO 2 was 42.5%.
[0050] The melting temperature for making the high-temperature frit is 1500°C.

Abstract
The invention provides transparent glaze and a manufacturing method thereof, and relates to glaze for ceramic. The transparent glaze compries the following components in percntage by mass: 0.2 to 2 percent of Na2O, 0.5 to 5 percent of K2O, 9 to 12 percent of Al2O3, 4 to 8 percent of CaO, 1 to 5 percent of MgO, 0 to 10 percent of ZnO, 2.0 to 4 percent of ZrO, 10 to 30 percent of high-temperautre frit with the loss on iginition of 1 to 6 percent, and the balance of SiO2. The transparent glaze is prepared by th steps of throwing materials according to the ratio, performing ball milling, measuring the residue rate, grinding, adjusting the proportion to be 1.35 to 1.4, glazing, firing and obtaining the finished product. Sodium potassium feldspar is replaced by potassium feldspar and the high-temperature frit is added, so that the firing range of the transparent glaze is increased, the starting melting point of glaze water is reduced, the glaze firing temperature is prevented from lowering, the glaze can be burned at the temperature of 1,260 DEG C while the glaze surface is not overburned, zinc oxide is reduced from 8 to 2.5, and stained paper in the glaze burned at the temperature of 1,060 DEG C can be precipitated into the glaze.
Description
technical field [0001] The invention relates to a ceramic glaze, in particular to a transparent glaze and a manufacturing method thereof. Background technique [0002] In the prior art, ceramic products have a broad market because of their high density. Nowadays, there are more and more kinds of ceramic products, the colors are brighter and brighter, the decorative effect is more natural, and the three-dimensional effect is also stronger and stronger. However, the surface gloss of the polished tiles in the prior art is not natural, and the texture of the patterns cannot be improved. The decoration effect is not ideal, the product is easy to be stained, the thickness of the glaze is high, the glaze is rough, and the material selection is strict, the yield is low, the product grade is affected to a certain extent, the cost is high, and the customer needs a natural texture and durability. Good grinding and good decorative effect. [0003] VB is the abbreviation of VILLEROY&BO...
