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.
