Embodiment 1
[0032]Example 1: On the 480mm bone china vase blank, draw the outer contours of the dragon and phoenix with a brush dipped in tearable glue, and then apply a layer of golden yellow glaze on the outer surface of the 480mm bone china vase blank , golden yellow color glaze prepared according to the following formula: 25 parts of quartz powder (325 mesh), potassium feldspar powder (325 mesh): 25 parts, 10 parts of kaolin, 12 parts of borax, 5 parts of zinc oxide, 1 part of zirconium silicate, carbonic acid 11 parts of calcium, 5 parts of phosphorus pentoxide, 1 part of strontium carbonate, and 5 parts of lithium carbonate. After mixing the above raw materials evenly, melt them at 1400℃~1450℃, put them into cold water and quench them into a frit. Put the frit into a ball mill, add water, high alumina ball stone and 6% kaolin to grind it into a glaze slurry, the fineness is controlled to be less than 0.03% on a million-hole sieve, and then dried at 70-100°C to make a powder over 250...
Embodiment 2
[0035] Embodiment 2: On the 400mm hard porcelain flat plate compact, use a brush to dip in paraffin to draw the outline of the peony flower, and then apply a layer of bright red color glaze on the outer surface of the 400mm hard porcelain flat plate compact, The bright red color glaze is prepared according to the following formula: 44 parts of quartz powder (325 mesh), nepheline powder (325 mesh): 20 parts, 6 parts of kaolin, 8 parts of borax, 6 parts of zinc oxide, 1 part of diyttrium trioxide, calcium carbonate 9 parts, magnesium carbonate 2 parts, strontium carbonate 2 parts, lithium carbonate 2 parts. After mixing the above raw materials evenly, melt them at 1450°C, put them into cold water and quench them into frits. Put the frit into a ball mill, add water, high alumina ball stone and 10% kaolin to grind it into a glaze slurry, the fineness is controlled to be less than 0.03% on a 10,000-hole sieve, and then dried at 80°C to make a powder and pass through a 250-mesh siev...
