Black glaze cup adobe vintage formula and preparation method

Abstract

The invention discloses a black glaze cup adobe vintage formula and a preparation method. The black glaze cup adobe vintage formula comprises the following raw materials of blank, plant ash and iron ore, wherein the blank is prepared from 5 parts of feldspar, 3 parts of quartz, 2 parts of akaishi, 2 parts of herba szechwan podocarpii, 5 parts of iron red powder and 5 parts of red soil, the plant ash burnt by plants and the iron ore are taken as glaze; the chemical ingredients of black glaze cup dry substances is 4-8% of Fe2O3, 6-9% of CaO, 2-5% of MgO, 15-20% of Al2O3 and 2-4% of P2O5. The preparation method comprises the following steps: S1: making earth; S2: making glaze; S3: applying the glaze for the first time; S4: drying for the first time; S5: applying the glaze for the second time;S6: carrying out drying and forming for the second time. In S1, 5 parts of feldspar, 3 parts of quartz, 2 parts of akaishi, 2 parts of herba szechwan podocarpii, 5 parts of iron red powder and 5 parts of red soil are selected and mixed, a proper quantity of water is added, a simple ball mill is adopted for grinding, grinding time is 48 hours, and then, the ground mixed materials are sieved. In the black glaze cup adobe compound formula, the contents of Fe2O3 are ensured, and a burnt sintering product can achieve enough blackness.

Description

Technical field [0001] The invention relates to the technical field of black-glazed cups, in particular to a black-glazed cups embryonic retro formula and preparation method. Background technique [0002] The black glaze cup is one of the most typical tea sets in the Song Dynasty. It was produced in large quantities for the needs of ordering tea and fighting tea. Song people fighting tea must use the precious "Jian Gao". According to Cai Xiang’s “Tea Records” in the first record: “It was created by Jian’an, the wrong black, if the pattern is free of it, it is still slightly thick, dry for a long time, hot and cold, the most useful.” The black base of the Song Dynasty is used to build secrets. As a representative, one of the main reasons is that the Yecha Garden in the Song Dynasty is located in the Fenghuangshan area of ​​Jian'ou, Fujian. The electricity production of Longfeng Tuanbing Tea further stimulated the development of Jianmi porcelain. [0003] However, the existing black...

Problems solved by technology

[0003] However, the existing ancient formula and preparation method of black-glazed calyx clay cannot ensure the content of Fe2o3, and the fired products cannot achieve sufficient blackness, and the glaze prepared by the existing method is not high in brightness. At the same time, the artistic appeal is not strong, so it is necessary to design a retro formula and preparation method of black glazed clay
