Abstract

The invention provides emerald green glaze which is prepared from, by weight, 10-16 parts of primary medicines, 39-45 parts of melilite, 11-17 parts of quartz, 13-19 parts of calcite, 4-6 parts of talcum, 3.5-4.3 parts of iron ores, 0.08-0.12 part of chromium oxide and 5-7 parts of zinc oxide. Compared with the prior art, the emerald green glaze has the advantages that iron and chromium serve as coloring agents and are fired in reducing atmosphere to form the emerald green glaze, and the emerald green glaze with pure natural colors, strong jade texture and opalescence and high yield can be prepared by firing without removing iron in raw materials.

Description

technical field [0001] The invention relates to a glaze material, in particular to an emerald green glaze. Background technique [0002] Jun porcelain is based on the thickness of the glaze. Its color is either sunken at the bottom of the glaze, or suspended in the glaze, or floating on the surface of the glaze. Jun porcelain is transformed into a god by the kiln, and the natural transformation of the kiln is the essence of Jun porcelain art, and it is also the rarity of Jun porcelain that is famous all over the world and famous in the porcelain forest. The same kind of glaze is applied during firing, and once fired, it will be colorful, that is, "one color when entering the kiln, and many colors when leaving the kiln". The ever-changing kiln transformation effect forms the magic of endless color changes. The dividends are purple, purple is dark blue, blue is white, white is red, and the colors are infiltrating and shining. known as. [0003] The key to Jun porcelain lies...
