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 for medium-temperature firing through-flower porcelain and a preparation method for medium-temperature firing through-flower porcelain. Synthetic flux is added to the blank of the invention, and multiple flux components are combined to exert a composite fluxing effect. In the case of not increasing the amount of flux, the firing temperature is greatly reduced; the preparation steps of the medium-temperature firing through-flower porcelain of the present invention include preparing blanks, grouting molding, carving through-flowers, kneading and pasting porcelain flowers, and glazing. Firing in an oxidizing atmosphere at 1280°C, painted and decorated, and baked at 750-800°C. The present invention greatly reduces the firing temperature of the through-flower porcelain through the experimental research on the formula of synthetic flux, blank and glaze, and oxidizes and fires the through-flower porcelain at a medium temperature of 1250°C, so that all the medium-temperature colorants can be stabilized The color development greatly enriches the color of Tonghua porcelain, and the appearance is more beautiful, and the firing temperature is low and the firing cycle is short. The invention not only saves energy and reduces consumption, but also improves the quality grade 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. ...
