Embodiment 1

[0040] Embodiment 1: a kind of Longquan celadon jasper green glaze, according to its total amount is 100% weight percent, it is made of the glaze material of following components: potassium feldspar 40%, quartz 15%, purple gold soil 20% , Limestone 10%, Fluorite 8%, ZnO 4%, SnO 2 3%. Among them, ZnO is ZnO powder calcined at 1250-1280°C before batching. After calcining, it can reduce the shrinkage of the glaze during the firing process, reduce defects such as air bubbles and pinholes, increase the density of the glaze and improve the performance of the glaze.

Embodiment 2

[0041] Embodiment 2: a kind of Longquan celadon jasper green glaze, according to its total amount is 100% weight percent, it is made of the glaze material of following components: potassium feldspar 35%, quartz 18%, purple gold soil 20% , Limestone 11%, Fluorite 9%, ZnO 3.5%, SnO 2 3.5%. Among them, ZnO is ZnO powder calcined at 1250-1280°C before batching.

Embodiment 3

[0042] Embodiment 3: a kind of Longquan celadon jasper green glaze, according to its total amount is 100% weight percent, it is made of the glaze material of following components: potassium feldspar 42%, quartz 17%, purple gold soil 18% , Limestone 10%, Fluorite 6.5%, ZnO 4%, SnO 2 2.5%. Among them, ZnO is ZnO powder calcined at 1250-1280°C before batching.

Abstract

The invention relates to Longquan celadon jasper green glaze, a jasper green Longquan celadon product and a preparation method of the product.The Longquan celadon jasper green glaze is prepared from, by weight, 30-50% of potassium feldspar, 10-20% of quartz, 15-25% of violet gold, 7-13% of limestone, 6-10% of fluorite, 3-5% of ZnO and 2-4% of SnO2, wherein the total percentage of all the ingredients is 100%.On the basis of ensuring the traditional aesthetic effect of Longquan celadon, the violet gold with the high iron content is introduced as a coloring agent, meanwhile, the ZnO and the SnO2 are introduced as emulsion, the Longquan celadon glaze similar to jasper in appearance, color and texture is obtained by adjusting the formula of the glaze, and the purpose of enriching colors and enamels of Longquan celadon is achieved.

Description

technical field [0001] The invention belongs to the technical field of Longquan celadon production, in particular to a Longquan celadon jasper green glaze, jasper green Longquan celadon product and a preparation method of the product. Background technique [0002] Jasper is a kind of jade in my country. It is a chemical deposition product related to volcanic-hydrothermal activities. Its appearance color can be green, dark green, dark green, and its color distribution is relatively uniform. It has a grease-waxy appearance. Gloss, transparency is generally slightly transparent or opaque, and its main components are MgO, SiO 2 , CaO, and a small amount of FeO, the color of jasper is proportional to the content of FeO. However, the content of natural green iron ore is a non-renewable resource after all, especially the iron ore with good color is less, and the mining cost and selling price are high, which makes it unaffordable for many people who love jade. Therefore, how to use ...
