Abstract
A process for preparing verdure ceramic utensils belongs to the technical field of preparing ceramics, which comprises a baking procedure and is characterized in that in a kiln, after being sintered at a temperature of 850-1050DEG C, dry bodies of the utensils are smoldered for 50-90 minutes by employing piney boughs as combust under strongly reducing atmosphere and then an air inlet duct and an exhaust chimney are sealed for stuffy making for 30 hours. The verdure ceramic utensils of the invention have the advantages of strong strength, ageing resistance and corrosion prevention and can be applied in tea set, cook ware, dinnerware and craftworks of flower pots with comparatively high service value and visual value.
Description
Technical field
The invention belongs to the preparing technical field of pottery, be specifically related to a kind of preparation method of celadon pottery vessel.The blue or green pottery of the present invention's preparation is mainly used in daily life potteries such as drinking-water apparatus, tableware, cooker, flowerpot artwork.
Background technology
Pottery is meant with the clay to be tire, pinch, take turns method machine-shapings such as system, molding through receiving and distributing after, the article that roasting forms under 800～1000 ℃ of high temperature, base substrate is opaque, and micropore is arranged, and has water-absorbent, the sound of kowtowing is unclear.Pottery can be divided into thin pottery and crude pottery, and is white or coloured, no glaze or glaze is arranged.Kind has gray pottery, red pottery, white pottery, ancient painted pottery, black pottery etc.Have dense vitality and unique artistic style.As far back as the Shang dynasty, the hard glazed pottery of glazed pottery and first tool porcelain character has just appearred.
By retrieval, find no the document of firing blue or green pottery.
Summary of the invention
The pottery that the purpose of this invention is to provide a kind of iron cyan, its intensity is bigger, and stronger anti-aging, anticorrosive effect is arranged, and is applied to daily necessitiess such as tea set, cooker, tableware, flowerpot artwork and has higher use value and ornamental value.
Another object of the present invention has provided the described blue or green preparation method who makes pottery.
The following technical scheme of the concrete employing of the present invention:
A kind of preparation method of celadon pottery vessel, comprise ablating work procedure, it is characterized in that, in kiln, the vessel dry body adopts pine branch to make the fuel 50～90min that smoulders under reducing atmosphere behind 850～1050 ℃ of sintering temperatures, shuts air inlet duct and gas shaft then, vexed system 30 hours, vexed system finish and add water cooling or naturally cool to the normal temperature kiln discharge in kiln.
Described smouldering is that air inlet duct with kiln is shut, and gas shaft is shut 70～80%, and pine branch burns under anoxic condition and forms strongly reducing atmosphere.
The preparation method of described celadon pottery vessel specifically may further comprise the steps:
1) selects materials: according to standby after the yellow clay 40% of weight percent, red clay 40%, black clay 20% mixing and ball milling;
2) moulding: pug put into stir the mud machine and stir pugging repeatedly, then through throwing or mechanical-moulded, repaired biscuit, polishing, oven dry or natural drying become dry body;
3) fire: dry body is packed in the kiln, fires with the mode of heating gradually, treat that temperature is elevated to sintering state after, smoulder with grease-contained pine branch or oiliness combustiblematerials formation reducing atmosphere again, just be formed with the iron cyan pottery of metalluster.
Pine branch of the present invention can adopt bituminous coal to substitute, particularly high-quality bituminous coal.
Sintering of the present invention can adopt coal, timber or other heating fuels commonly used to carry out.
Firing atmosphere of the present invention is meant in the process of firing, the per-cent of contained free oxygen and reduction composition in the products of combustion in the kiln, to fire stage free oxygen content be 3%-6% in oxidation in early stage, is higher than 6% to the smoulder content of stage free oxygen content carbon monoxide less than 1% of the strong reduction in later stage.
Beneficial effect of the present invention is: the present invention adopts the combustiblematerials of pine branch or oiliness to fire in strongly reducing atmosphere; form the iron cyan reduction-oxidation film that one deck has metalluster on the pottery surface; formation is to the protection of pottery; make pottery of the present invention anti-aging, corrosion-resistant; simultaneously simple and unsophisticated generous, have very high ornamental value.
Embodiment
Embodiment
1) batching: select local yellow clay 40Kg, red clay 40Kg, black clay 20Kg for use, it is standby to carry out ball milling.
2) moulding: pug put into stir the mud machine and stir pugging repeatedly, then through throwing or mechanical-moulded, repaired biscuit, polishing, oven dry or natural drying become dry body;
3) fire: begin slowly to dry by the fire and burn about four hours temperature and keep about 200 °, be warmed up to 600 ° then gradually and took time approximately 8 hours, begin big fire again and be warmed up to and took time approximately about 850-1050 ° 6 hours, kept this temperature 50～90 minutes with little fire.
4) smoulder: behind the sintering, add in kiln and have greasy pine branch in a large number, the air inlet duct of kiln is shut, gas shaft is shut 70～80%, the 50～90min that smoulders under reducing atmosphere shuts air inlet duct and gas shaft then, and vexed system is about 30 hours.
5) kiln discharge: in vexed system process, add water cooling or protect the gas naturally cooling and just formed glossiness iron cyan pottery.
Sintering temperature of the present invention is relevant with the size of institute's cloisonne pottery tool, for example: if fire the bigger utensil of volume, for example: large-scale flowerpot, sintering temperature is higher, from the upper limit; If the utensil volume of firing is less, for example: drinking-water apparatus, tableware, sintering temperature is lower, from lower limit.
