The wax protection glaze is introduced with higher content of divalent metal compounds such as barium oxide, calcium oxide and the like as a cosolvent, compared with the wax protection glaze which takes univalent oxide as the cosolvent, the wax protection glaze has wider firing range and smaller expansion coefficient, and the fired glaze surface has good glossiness and elasticity. The calcium oxide can be introduced through dolomite and calcite, and the calcium oxide and silicon dioxide form glass, so that the transparency of the glaze can be improved, but the dosage of the calcium oxide is not too large, otherwise, the devitrification tendency of the glass is increased, and the devitrification phenomenon is generated. The barium oxide is mainly introduced by barium carbonate, and the barium carbonate can reduce the melt viscosity and improve the glossiness and the wear resistance of the glaze, but the excessive use amount of the barium carbonate can also generate the crystallization phenomenon. Therefore, the glaze surface can achieve ideal luster by adding proper amounts of barium carbonate and calcium carbonate.

Fig. 8 is a pictorial representation of a waxy ceramic tile of comparative example 1, where fig. 8 is less three-dimensional and layered than fig. 5 (example 3), and is less tactilely appealing than the waxy ceramic tile of example 3.
FIG. 9 is a pictorial representation of a wax-based ceramic tile of comparative example 2, wherein FIG. 9 is less textured than FIG. 6 (example 4). Since the depressed regions of comparative example 2 were formed only with the carved ink, the gloss and the cubic effect of the intaglio were relatively single.
Fig. 10 is a pictorial representation of a waxy ceramic tile of comparative example 3, with fig. 10 showing a less uneven texture than fig. 3 (example 1). The depressed region of comparative example 3 was formed only with depressed ink, and thus the color texture and cubic effect of the depressed grain were relatively single.
The gloss of the waxy protective glaze surfaces of comparative example 4 and example 2 was measured using a cushi WGG60 photometer. The corresponding test results are as follows:
| example 2 | Comparative example 4 | |
| Degree of |
11 | 7 |
In comparative example 4, the barium carbonate content of the waxy protective glaze is less than that of examples 1-4, and the glossiness of the waxy protective glaze surface obtained by firing is only 7 degrees and does not meet the requirement of 9-13 degrees. Comparing fig. 11 with fig. 4 (example 2), it is also apparent that fig. 11 lacks gloss.
In comparative example 5, the barium carbonate content of the waxy protective glaze was higher than that of example 2, and as can be seen from fig. 12, the pattern of fig. 12 was hazier and less distinct than that of fig. 4 (example 2). With the continuous increase of the addition of barium carbonate, a barium feldspar crystalline phase is gradually formed in the firing process, the transparency of the glaze layer is reduced instead, the pattern effect is not easy to be clearly shown, the price of barium carbonate is high, and the cost is increased due to excessive use.
In comparative example 6, the waxy protective glaze had less calcium oxide than in example 1, and as can be seen from fig. 13, the pattern of the waxy ceramic tile of comparative example 6 was hazy and less distinct than that of fig. 3 (example 1). When the dosage of the dolomite and the calcite is too low, the content of the introduced calcium oxide is not enough, so that the transparency of a glaze surface is not enough, and the clear presentation of a pattern effect is not facilitated.
In comparative example 7, the calcium oxide content of the waxy protective glaze was greater than that of example 1, and it can be seen from fig. 14 that the pattern of the waxy ceramic tile of comparative example 7 was also blurred and less distinct than that of fig. 3 (example 1). When the dosage of the dolomite and the calcite is too large, the calcium oxide is too much, the tendency of glass crystallization in a glaze surface is increased, the transparency is reduced, and the clear presentation of a pattern effect is not facilitated.
The maximum pit depths were determined for the waxy ceramic tiles of examples 1-15, and comparative examples 2-3, and the corresponding results are shown in tables seven, eight, and nine:
TABLE VII:
in table seven, the engraving ink and the sinking ink of each of examples and comparative examples each had a printing gray of 80, wherein examples 1 to 7 all formed a texture layer using the engraving ink and the sinking ink, while comparative example 2 used only the engraving ink and comparative example 3 used only the sinking ink. As can be seen from the results of table seven, the depth of the intaglio was much smaller in comparative examples 2 and 3 than in examples 1 to 7, indicating that it is difficult to obtain an intaglio with a large depth using only the engraved ink or the depressed ink alone. In examples 1 to 7, when the width of the printed line is 0.5 to 1.9mm, the depth of the intaglio can be 0.2mm or more, which is 5 times or more of the effect of using the fine engraving ink or the sinking ink alone.
Table eight:
in table eight, the print line widths of the finishing engraving ink and the sinking ink of each of examples and comparative examples were 0.7mm, wherein examples 1 and 8 to 12 each formed a texture layer using the finishing engraving ink and the sinking ink, while comparative example 2 used only the finishing engraving ink and comparative example 3 used only the sinking ink. From the results in Table seven, it can be seen that comparative examples 2 and 3 also have a depth of the intaglio that is smaller than examples 8 to 12, and particularly much smaller than examples 1 and 9 to 12.
Table nine:
it can be seen from table nine that when the printing gray scale of the engraving ink and the sinking ink is 80 and the line width is 0.5mm, the depth of the intaglio can still reach 0.2mm. When the line width is 0.3mm, the depth of the intaglio becomes remarkably shallow. When the printing gray scale of the fine engraving ink and the sinking ink is 80 and the line width is 0.5mm, the using amount of the fine engraving ink and the sinking ink is the least, and a better intaglio effect can be achieved.
In conclusion, the wax glaze with rich brightness and concave grain effect is formed by matching the finishing engraving ink, the sinking glaze and the wax protective glaze, and the texture effect of the glaze is further enriched by partially embedding the dry grain glaze in the sinking area, so that the wax glaze has 3D (three-dimensional) feeling.
The invention further improves the formula of the wax protective glaze, so that the wax protective glaze has better glossiness and good transparency, can clearly express the pattern layer, and enriches and diversifies the overall texture pattern.
It should be understood that equivalents and modifications of the technical solution and inventive concept thereof may occur to those skilled in the art, and all such modifications and alterations should fall within the scope of the appended claims.
