Formula of Longquan celadon bead-shaped ornament and preparation method thereof

Abstract

The present invention discloses a formula of a Longquan celadon bead-shaped ornament and a preparation method thereof. The formula comprises a blank and a glaze. Counted in parts by weight, the blank comprises 8-15 parts of quick lime, 20-35 parts of phosphorus pentoxide, 15-20 parts of silica, 1-5 parts of sandstone and 20-40 parts of china clay. Counted in parts by weight, the glaze comprises 30-40 parts of glaze clay, 10-30 parts of wollastonite, 10-25 parts of Longyan clay, 1-5 parts of black mud, 1-5 parts of Fangzi soil and 5-10 parts of fluorite. The above raw materials are sequentially subjected to the steps of manufacturing the blank mud, preparing the glaze slurry, forming a blank, firing a biscuit, glazing, threading, suspending, firing and subsequent polishing, so that a prepared bead-shaped ornament is relatively high in hardness. Meanwhile, the glaze can be completely and uniformly covered onto the ornament. The glaze surface of the ornament is fine, smooth, and high in jade texture. Fine bubbles on the glaze layer of the ornament are uniform and fine.

Description

[0001] technical field [0002] The invention relates to a formula of porcelain ornaments and a preparation method thereof, in particular to a formula of Longquan celadon bead ornaments and a preparation method thereof. Background technique [0003] Longquan celadon is a treasure of Chinese traditional porcelain making. During the Southern and Northern Dynasties, people from Longquan, Zhejiang made use of the local superior natural conditions to manufacture celadon. The outstanding representative of Longquan celadon at the present stage was as early as the Southern Song Dynasty, when the powder green glaze and plum green glaze that were as crystal as jade were fired, reaching their peak, green as jade, bright as a mirror, thin as paper, and sound like a chime.
