Jun-porcelain wood burning glaze

Abstract

The invention relates to a jun-porcelain wood burning glaze. The glaze is prepared from, by weight, 28-35 parts of quartz, 19-23 parts of potassium feldspar, 7-12 parts of albite, 15-18 parts of plant ash, 10-15 parts of limestone, 3-4 parts of talc and 1-2 parts of ferric oxide. The purposes of making the glaze surface of prepared jun porcelain cyan, making the glaze color uniform and mild and making the glaze surface slightly yellow can be achieved, and the jun-porcelain wood burning glaze has the advantages of being low in cost and high in rate of finished products.

Description

technical field [0001] The invention relates to the field of Jun porcelain glazes, in particular to a Jun porcelain firewood glaze. Background technique [0002] Firewood firing is a traditional ceramic firing process that uses firewood as fuel. It is an ancient firing method. Since the beginning of ceramics, people have been firing ceramics with firewood. In the era of increasingly advanced modern kiln firing technology, the original way of firewood to make pottery has become another choice for potters who pursue texture. During the firewood burning process, the kiln chamber is filled with firewood ash, and the main components of firewood ash are mineral components such as carbonate and nitrogen, phosphorus, potassium, calcium, and magnesium contained in plants. These minerals will melt into "glaze" at a high temperature above 1300°C, that is, "grass gray glaze". Because the main component of firewood ash is calcium carbonate, together with the mineral components such as...
