Problems solved by technology

[0004] The formula and firing process of ancient Tianmu glaze have long been lost. Now some research experts have the following technical problems in the glaze formula and firing method: First, due to the uncertainty of the formula and firing method, Yaobian Tianmu in the prior art Obtaining the glaze effect is extremely accidental and unstable. It is often difficult to obtain a piece of porcelain with the glaze effect of Yaobian Tianmu even after tens of millions of firings. The rate of finished products of Yaobian Tianmu firing is extremely low
Secondly, it is difficult to form a clear color-changing halo in the glaze effect obtained by the existing firing method. The formation of the halo in the prior art is accidental, and the halo is an important feature of the glaze effect of Yaobian Tianmu
Finally, although the existing glaze formulations can obtain the effect of oil droplets, celestial eyes and scorpions after kiln transformation, the yield is relatively low, and it is difficult to produce in batches

Abstract

The invention discloses a novel temmoku glazed porcelain and a firing method thereof, belongs to the technical field of preparing high-end artistic ceramics and in particular relates to a novel glaze formula, a novel green body material formula and a special firing method. The firing method comprises a special heating curve and five-step stepladder temperature rising and descending, wherein in the temperature descending step, a method of stepladder temperature descending and rising for multiple times is adopted to promote formation of halo in a glaze surface. According to the novel glaze disclosed by the invention, the effects of the glaze surfaces of oil droplet temmoku, hare's fur temmoku and yaobian temmoku can be achieved, and three kinds of famous ceramics in ancient times can be fired by one glaze, so that the novel glaze is a new innovation and creation and is high in yield. According to the firing method disclosed by the invention, in the obtained yaobian glaze surface effect, the amount of spots is large, and a boundary between two adjacent spots is clear; in addition, the preparation process and method have the actions of guidance and reference to high-tech ceramics and have very high scientific and market values.

Description

Technical field [0001] Tianmu glaze porcelain and its firing method belong to the technical field of high-end artistic ceramic preparation. Background technique [0002] Tianmu glaze is a kind of precious glazed porcelain produced in the Song Dynasty in my country. The phoenix and feathers are now handed down. The Yaobian Tianmu is even more rare and rare. Only three are collected in giant safes in three museums in Japan, and they are only displayed every seven years. once. my country has not yet discovered that Yaobian Tianmu glaze porcelain has been handed down to the world. Therefore, since the 19th century, ceramic experts from all over the world have invested a lot of manpower and material resources to try to copy this famous porcelain, but it has not been reported that the successful copying is recognized by the industry. [0003] Ancient Tianmu glaze porcelain mainly included three varieties: Youdi Tianmu, Tuhaotianmu and Yaobiantianmu, which were fired from three glazes. T...
