Description

A kind of preparation method of Buddhist public affairs pottery handicraft

Technical field

The present invention relates to pottery technology field, more particularly to a kind of preparation method of Buddhist public affairs pottery handicraft.

Background technology

Ceramics are one of important components of Chinese culture, and pottery is one in Chinese Ceramics Culture bright bright Pearl.Pottery rises in the Eastern Han Dynasty, is one of five big kiln porcelain of Song Dynasty, is the treasure in traditional technology in producing porcelain, with the transmutation of uniqueness Art and be world-famous for, be known as " the valuable an ancient unit of weight average price of gold " and the good reputation of " there is ten thousand strings of cash in family, be not as a piece of as pottery ".Pottery is described as It is the special product of China Countermeasure In Yuzhou City of Henan Province first of Chinese " five big porcelain ", it is mainly characterized by the color of porcelain and complicated, and changes The single colour glaze development grain of ancient times porcelain, there is unique characteristics such as " enter kiln is of the same colour, kiln discharge ten thousand is color ", be other ceramic processes What product can not be realized and compare.But when making pottery, although although present technology has had been achieved with remarkable progress, Or some defects be present, pottery, from sorting to finished product is fired, will pass through tens of road production processes, nothing therebetween in manufacturing process Careless slightly by which procedure, even slight mistake will also result in that all that has been achieved is spoiled, and this is also the extremely low original of pottery treasure rate Cause, the key of pottery are enamel, and enamel chatoyance after being fired by glaze decides the value of pottery, and when firing, pottery is going out Easily ftractureed after kiln cooling, so as to cause treasure rate low.

The content of the invention

In view of this, the present invention provides a kind of preparation method of Buddhist public affairs pottery handicraft, and glaze-body bonding performance is good, yield rate It is high.

To achieve the above object, the present invention uses following technical scheme：

A kind of preparation method of Buddhist public affairs pottery handicraft, comprises the following steps：

Step 1, engraving model；Whole handicraft is divided into some to carve respectively, including head, hand, leg, beads and Main body, wherein hand, which are put one's palms together devoutly, is put in front, and beads are placed at the wrist of both hands, and hand and beads are put in the robe of main body Outside；Leg both legs are sat crosslegged, outer in the robe pendulum of main body；

Step 2, make mould；The some that step 1 is carved to shaping makes gypsum mold respectively；

Step 3, choose clay；The clay includes following components：Kaolin 65-75%, sandstone 8-15%, lead powder 8-12%, Mo Lai Stone 8-12%, iron ore 1-2%, cobalt oxide 0.2-0.4%, dietary alkali 0.3-0.5%；

Step 4, slurrying；The clay of step 3 is carried out to coarse crushing first into sand shape or powdery, then ground, it grinds carefully Spend for 230-250 mesh, add water mix after ball milling, slurry is made；

Step 5, injection forming；Slurry is injected separately into each mould in step 2, and by multiple moulds after slip casting The base substrate of generation is solidified, is bonded together according to design requirement, by finishing, forms overall image；

Step 6, dry；The base substrate trimmed is dried at a temperature of 25-120 DEG C, dried base substrate water content is less than 3%；

Step 7, biscuiting；Base substrate is put into biscuit kiln, 5-6 hour is fired at a temperature of 900 DEG C -1000 DEG C；

Step 8, glazing；By after biscuiting billet surface removal of impurities processing after carry out surface apply glaze material, wherein head, hand, leg, Beads and bottom not glazing, main part using brushing glazing either glaze spraying or dip in glaze method carry out glazing；Glaze be by including Melilite 50-60%, white feldspar 8-12%, calcite 8-11%, Copper Ores 1-3%, zinc chloride 3-5%, barium carbonate 0.1-0.4%, oxygen Change tin 0.1-0.8%, di-iron trioxide 5-7%, potassium oxide 1-3%, sodium oxide molybdena 0.5-1%, kieselguhr 3-8% glaze is crushed, Mixing, ball milling, it is 400-450 targeted fine powders to become fineness, adds water that glaze slip is made after being stirred ball milling；

Step 9, fire；By after glazing and the base substrate dried is put into kiln that to fire 12-15 in 1280 DEG C -1300 DEG C of temperature small When.

Beneficial effects of the present invention are：

Potassium oxide and sodium oxide molybdena are added in the glaze of the present invention, the melting temperature and high temperature viscosity of glaze is reduced, improves the change of glaze Stability and heat endurance to be learned, makes glaze that there is good transparency and glossiness, glaze-body bonding performance is good, while using the present invention Clay, glaze and making step, the high yield rate of pottery, its device shape and color can more embody the intention and skill of works of the present invention Art effect.
