Problems solved by technology

To reduce the firing temperature of ceramics, the usual method is to increase the proportion of flux components in the blank. Since the flux is a barren mineral, it will inevitably have an adverse effect on the plasticity and water retention of the blank; at the same time, due to the clay with good plasticity The content of impurities is high, which will cause adverse effects on the whiteness and light transmittance of the porcelain blank after adding, and the amount of addition is limited

Abstract

The invention discloses a blank material use for preparing a porous decorated porcelain by intermediate-temperature firing and a porous decorated porcelain preparing method by intermediate-temperature firing. A synthetic flux is added into the blank material, a composite fluxing function is exerted by combination of a plurality of flux components, and the firing temperature is largely reduced under a circumstance of not increasing the using amount of the flux. The method includes steps of preparing the blank material, moulding by slip casting, sculpturing, making porous patterns, kneading and pasting porcelain patterns, glazing, firing in an oxidation atmosphere having a temperature of 1250-1280 DEG C, performing colored drawing, decorating and roasting at 750-800 DEG C. By tests and research on the synthetic flux, the blank material, glaze, and other formulas, the firing temperature of the porous decorated porcelain is largely reduced, the porous decorated porcelain can be prepared by oxidation and firing at an intermediate temperature of 1250 DEG C, and therefore coloring of all intermediate colorants can be stable, the color of the porous decorated porcelain is largely enriched, and the appearance is more beautiful. The firing temperature is low and the firing period is short. The method saves energy, reduces consumption, and increases the grade of quality of products.

Description

technical field [0001] The invention relates to a blank for medium-temperature firing through-flower porcelain and a preparation method for medium-temperature firing through-flower porcelain, belonging to the technical field of inorganic non-metallic material synthesis. Background technique [0002] Tonghua Porcelain is a kind of carved and hollowed out decorative art with unique local characteristics in Fengxi, Chaozhou. Using the art of three-dimensional hollowing out, engraving transparent geometric patterns on the porcelain body, posting flowers of different shapes hand-kneaded, after firing, there is an artistic effect of white as jade, thin as paper, and thin as silk. After being hand-painted or spray-painted, after roasting, it looks like a flower, and it is difficult to distinguish the true from the false. In order to meet the needs of carving hollows and hand-kneading flowers of different shapes, the blanks are required to have good plasticity and water retention. ...
