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.
