Description
Technical field
The present invention relates to a kind of preparation method of charcoal golden metallic luster crystalline glaze.
Background technology
Metallic luster crystalline glaze is that glaze produces the outer appearnce such as color harmony gloss like certain metal and contains the ceramic glaze of xln, is a kind of new ceramics artistic glaze that developed recently gets up.It not only has the aesthetic feeling of luster effect and the xln of metal, and has the characteristics such as the ceramic glaze cost is low, hardness of glaze surface is high, wear resistance is good, corrosion-resistant.Metalluster is because tiny needle-like crystal densification interweaves to due to the strong reflection of light intensity, makes glaze present thick and heavy solid, luxurious gorgeous sensation.The report of metal gloss crystalline glaze is many, but not yet finds the report of charcoal golden metallic luster crystalline glaze at present.
CN1521145 discloses a kind of crystalline glaze with metallic luster for ceramic of building sanitation, it is with zinc oxide, silicon oxide or titanium oxide are the one-tenth eutectic substance of glaze, with low temperature frit, boric acid is for forming the Vitrea flux raw material of glaze, with cupric oxide, ferric oxide, manganese oxide, the metal oxides such as titanium oxide are tinting material, be prepared by common ceramic glaze production technique, impose on the surface of construction sanitary ceramic, by the quick continuous burnt that is fit to, adopt short insulation to educate the distinct temperature curve in brilliant cycle, glaze is formed have the glass-ceramic layer of metalluster, the such decorative effect of its existing metalluster, the physical strength that has again devitrified glass can be widely used in various architectural potteries, the surface decoration of sanitary ceramic ware.
CN100575310C discloses a kind of method of manufacturing golden yellow mirror surface glaze, this glaze comprises zinc oxide, rhombspar, titanium oxide, calcite, without lead frit, kaolin, silica powder, cupric oxide, manganese oxide, Vanadium Pentoxide in FLAKES, 11 kinds of raw materials of ferric oxide, wherein cupric oxide and manganese oxide are coloring oxide; During making, by wet ball grinding, then sieve, by the concentration of 45～60 degree Beaume allotment slurry, get bright and clean porcelain blank and soak to enter kiln behind the glaze and under 1160～1200 ℃ oxidizing atmosphere, fire and form, the flicker of gained finished product glaze golden light, sparkling, coloured and dazzling.CN100537487C discloses a kind of making method of placer gold glaze material, after this glaze burns till in 1170～1200 ℃ of oxidizing atmospheres fast, glaze Venus under the ordinary ray irradiation is magnificent, flashing, glittering, gorgeous luxurious especially under shining than the high light line, comprise borax, boric acid and sodium, two kinds of carbonate of potassium in the described glaze, also be added with quartzy and albite and a small amount of clay and some tinting materials.During making, first borax and carbonate are made frit, extremely pass through 250 mesh sieves with quartz, albite, clay and tinting material ball milling again after frit is pulverized, it is 0.15～0.3mm that the glaze layer is implemented thickness.The impact of calcining system on the glazed metal luster effect reported in " Chinese pottery industry " 2008 (04), adopting kaolin, quartz, feldspar etc. is raw material, prepare metal-lustrous glaze take manganese oxide, cupric oxide as the crystallization agent, inquired into the affect rule of the calcining systems such as firing temperature, soaking time on glazed metal gloss.The result shows: under current prescription formed, 1120 ℃ of lower glaze firing also were incubated 30 minutes, and at 820 ℃ of lower slow coolings to 620 ℃, glaze has good metalluster effect afterwards.
" Chinese pottery " 2008 (08) reported the impact of composition on the glazed metal luster effect, and adopting kaolin, quartz, feldspar etc. is raw material, and introduces cupric oxide, manganese oxide as the crystallization agent, the preparation metal-lustrous glaze.Inquired into SiO in the prescription

2Addition, adopt different calcining systems prepared simple to operate, control is convenient, is fit to the golden yellow metal-lustrous glaze that burns till fast.Calcining system, metal oxide addition, glaze layer thickness have been inquired into to the impact of glaze gloss.Adopt the SEM modern test technology that the glaze layer is carried out morphology observation, studies show that the crystal growth has certain orientation, and all be parallel to glaze layer surface arrangement.
Summary of the invention
The objective of the invention is:Aim to provide a kind of preparation method of charcoal golden metallic luster crystalline glaze, it not only has the aesthetic feeling of luster effect and the xln of metal, and have characteristics such as the ceramic glaze cost is low, hardness of glaze surface is high, wear resistance is good, weathering resistance is good, corrosion-resistant, be a kind of brand-new ceramic artistic glaze, can be used for decorative porcelain artwork and tableware for Western-style food.
Technical scheme of the present invention is:The preparation method of charcoal golden metallic luster crystalline glaze, the source of its glaze and consist of (mass parts): adopt 25～30 MnO
2Be crystallizing agent, 0.5～1.5 MoO
2With 0.5～1.5 V
