The transparent frit was prepared in the same manner as in example 1.
Comparative example 6
A ceramic tile was prepared according to a method different from that of example 9 in the formulation of the transparent frit. The transparent frit described in this embodiment comprises, by mass:
30% of glass powder, 20% of magnesia-alumina spinel, 15% of anorthite, 3% of zinc oxide, 24% of potassium feldspar, 3% of borax and 5% of fluorite.
The transparent frit was prepared in the same manner as in example 1.
Comparative example 7
A ceramic tile was prepared according to a method different from that of example 9 in the formulation of the transparent frit. The transparent frit described in this embodiment comprises, by mass:
30% of glass powder, 20% of magnesia-alumina spinel, 15% of anorthite, 3% of zinc oxide, 24% of potassium nitrate, 3% of borax and 5% of fluorite.
The transparent frit was prepared in the same manner as in example 1.
The color development of the tiles prepared in example 9 and comparative examples 4 to 7 was determined, and the test results were as follows:
table five:
in comparative example 5, the transparent frit is not added with potassium feldspar and potassium nitrate, and has a whitish color compared with that of comparative example 4 and is greenish and blue; the transparent frit of comparative example 6, with the addition of potassium feldspar, developed a whiter and greener color than comparative example 4; the transparent frit of comparative example 7, which had potassium nitrate added, developed darker color than comparative example 4, but too reddish to yellow, where the color developed for red was very noticeable. In example 9, potassium feldspar and potassium nitrate were added to the transparent frit, and the use of the potassium feldspar and potassium nitrate in a reasonable combination makes the tile more gentle to the red and yellow color.
It should be understood that equivalents and modifications to the invention as described herein may occur to those skilled in the art, and all such modifications and alterations are intended to fall within the scope of the appended claims.
