One-time-glazing tiger down spot tortoise-shell glaze ceramic and manufacturing technology thereof

Abstract

The invention relates to the technical field of ceramic manufacturing, in particular to a one-time-glazing tiger down spot tortoise-shell glaze ceramic and a manufacturing technology thereof. The one-time-glazing tiger down spot tortoise-shell glaze ceramic comprises a ceramic blank body and a tiger down spot tortoise-shell glaze, the iron content of the ceramic blank body is 7.8-8.3%, and the tiger down spot tortoise-shell glaze is prepared from potassium feldspar, quartz, dolomite, sodium pyroborate, calcium carbonate, zinc oxide crystal whiskers and yellow iron oxides. According to the one-time-glazing tiger down spot tortoise-shell glaze ceramic, the fired tiger down spot tortoise-shell glaze ceramic has the black brown bottom color, large-area golden yellow color lumps are shown on the black brown bottom color, black brown lines formed along with the zinc oxide crystal whiskers are formed in the golden yellow spot lines, and the effect of tiger down spots is formed; the inventionprovides a brand new ceramic decorative method, firing can be completed through one-time glazing, the method is of a positive significance in pushing development of the ceramic product, and the positive economic benefits are achieved.

Description

Technical field [0001] The invention relates to the technical field of ceramic manufacturing, in particular to a tiger-skin spotted tortoiseshell glaze ceramic with one-time glazing and a manufacturing process thereof. Background technique [0002] Tortoiseshell glaze is a kind of glaze with black, yellow and other colors interwoven and moisturized. The tortoiseshell glaze was created by the Jizhou kiln in Jiangxi during the Song Dynasty. A black glaze was applied to the surface of the blank, and then a mixed glaze of glass glaze containing lime and iron (Fe) was used to sway randomly to form irregular patterns. This iron (Fe) element, after roasting, will be yellowish-brown in color, contrasting with the black background and blending with each other, like a tortoiseshell, with a very peculiar beauty. [0003] Although the yellowish-brown in tortoiseshell glaze is recognized as the oxidative roasting of iron (Fe) element, the coloring mechanism is relatively clear, but the test fo...

AI Technical Summary

Problems solved by technology

[0003] Although the yellow-brown color in tortoiseshell glaze is recognized as the result of oxidative roasting of iron (Fe) elements, and the coloring mechanism has been relatively clear, but experiments have found that the yellowish-brown area of ​​the glaze surface is small when simply adding iron oxide to the glaze. , the characteristics of tortoiseshell patterns are not obvious, and the appreciation of the appearance of porcelain is poor

[0004] In order to solve the above problems, the invention patent application with the application number CN201711237439.6 discloses a tortoiseshell glaze and its firing method. The tortoiseshell glaze is modified by ferric oxide, and the modified ferric oxide Iron is used to configure the bottom glaze. It only needs to be fired once to produce a mixture of natural black and yellow colors. There is a big gap; in addition, this kind of tortoiseshell glaze needs to be glazed twice, and the manufacturing process is complicated
