Embodiment 1

[0028] A snowflake glaze, including bottom glaze and top glaze, adopts titanium-zinc-boron combination technology, uses titanium, zinc crystals and boron compounds to freely adjust the viscosity of the glaze and the shape of the glaze flower in the bottom glaze and top glaze To suit various types of appliances. Its crystallization agent is introduced by TiO2 and ZnO, assists crystal growth aids such as MgO, CaO, Li2O, etc. to make crystal growth and development, makes borax into frit, and the introduction of boron adjusts crystal shape and glaze viscosity.

[0029] The formulation of the specific glaze is as follows:

[0030] Bottom glaze: feldspar 100 parts, quartz 55 parts, calcite 15 parts

[0031] Titanium dioxide 8 parts Burnt talc: 6 parts Spodumene 20 parts

[0032] Zinc oxide (calcined) 10 parts Kaolin 15 parts

[0033] Surface glaze: 100 parts of boron frit, 20 parts of calcite, 15 parts of quartz

[0034] Kaolin 5 parts

[0035] The production ...

Embodiment 2

[0037] The glaze principle and manufacturing process of embodiment two are the same as embodiment one, mainly because the ingredients are different from embodiment one, and the formula of concrete glaze is as follows:

[0038] Bottom glaze: feldspar 100 parts, quartz 55 parts, calcite 15 parts

[0039] 15 parts of titanium dioxide, 6 parts of burnt talc, 40 parts of spodumene

[0040] Zinc oxide (calcined) 30 parts Kaolin 15 parts

[0041] Surface glaze: boron frit 100 parts, calcite 20 parts, quartz 30 parts

[0042] Kaolin 20 parts

[0043] The ideal chemical composition of the glaze according to the composition of the above-mentioned embodiment one and embodiment two is:

[0044] Base glaze: SiO 2 36-45%AL 2 o 3 8-12% CaO 5-8%

[0045] TiO 2 4-6% ZnO 10-25% Li 2 O 1-1.5%

[0046] MgO 0.5-1.5% The rest are impurities.

[0047] Top glaze: B 2 o 3 8-15% SiO 2 20-38%K 2 O 5-15%

[0048] CaO 5-10% and the rest are impurit...

Abstract

The present invention is one kind of medium temperature alabastrine glaze including priming glaze and overglaze and its preparation process. The medium temperature alabastrine glaze is prepared with crystallizing agent of TiO2 and ZnO, crystallizing assistant MgO, CaO, Li2O, etc, borax for regulating crystal shape and glaze viscosity. The preparation process includes the following steps: milling the material in a ball mill for 24 hr, 320 mesh sieving, diluting with water to 48-50 Be deg, 120 mesh sieving the glaze sluury, applying priming glaze and applying overglaze, and sintering at 1230- 1280 deg.c in a kiln to form the alabastrine glaze.

Description

Technical field: [0001] The invention belongs to a ceramic glaze and a production method thereof, in particular to a glaze preparation and a production method of new flower glazes for daily-use ceramics and decorative art porcelain. The appearance of this type of floral glaze is snowflake-like, milky white and transparent glass, with many beautiful flow patterns, and belongs to the field of ceramic glaze preparation. Glazed decoration for household and display ceramics. technical background: [0002] Flower glaze is a colorful decorative glaze for porcelain. It is one of the traditional glazes in ancient my country. It breaks through the limitation of single color glaze and forms changeable flowing patterns during the firing process. It appeared in the Tang Dynasty and prevailed in the Song Dynasty. The famous rose purple and cinnabar red of the Jun Kiln in the Northern Song Dynasty. Later generations have fired. Flower glaze porcelain is decorated with sky blue or moon w...
