Hawksbill fancy glaze and firing method thereof

Abstract

The invention discloses hawksbill fancy glaze which is prepared from a ground glaze body and a cover glaze body, wherein the ground glaze body is prepared from the ingredients by weight: 57 to 63 parts of feldspar, 16 to 25 parts of quartz, 8 to 15 parts of limestone, 2 to 5 parts of talc, 5 to 10 parts of ball clay, 1 to 2 parts of bone ash and 7 to 8 parts of ferric oxide; the cover glaze body is prepared from the ingredients by weight: 55 to 60 parts of feldspar, 8 to 16 parts of quartz, 16 to 21 parts of limestone, 3 to 9 parts of talc, 10 to 16 parts of ball clay, 3 to 6 parts of purple iron-containing soil and 0.1 to 0.2 part of thickener; the ferric oxide is modified. According to the hawksbill fancy glaze disclosed by the invention, the ferric oxide is modified, the modified ferricoxide can be used for preparing the ground glaze body, and a color-mixed mixture of natural black, yellow and the like can be fired out through only once firing; the hawksbill fancy glaze looks likehawksbill turtle carapace stripe porcelain, hue is vivid and moistened, the yellowish-brown stripe characteristic is obvious, and the hawksbill fancy glaze extremely has artistic value and ornamentalvalue.

The tortoiseshell glaze was created and fired in the Jizhou kiln in Jiangxi during the Song Dynasty. A black glaze was first applied on the surface of the blank, and then a mixture of glass glaze containing lime and iron (Fe) elements was applied randomly to form irregular patterns. This element containing iron (Fe) will be yellowish-brown after roasting, which contrasts with the black background and blends with each other, like a tortoise shell, with a very specific beauty. [0003] Although the yellow-brown color in tortoiseshell glaze is recognized as the result of oxidative roasting of iron (Fe) elements, and the coloring mechanism has been relatively clear, but experiments have found that ...
