Description
Technical Field
The invention relates to the technical field of porcelain burning, in particular to a full-glaze burning method for one-step molding of pot-shaped full-glaze porcelain.
Background
China is the home country of porcelain, and porcelain is an important creation of ancient workers. Colorful porcelain is one of the great inventions of ancient China, and the 'porcelain' and 'China' are the same words in English, which fully shows that the exquisite and absolute of the Chinese porcelain can be used as the representative of China. The high-grade porcelain has the manufacturing process difficulty which is far higher than that of the common porcelain, so the collection of the exquisite porcelain in the ancient royal rooms is not lacked. As one of luxuries of specialty products of ancient china, china has spread to various countries through various trade channels, and exquisite ancient china is collected as an antique having collection value by a large number of collectors. The formation of the glaze on the porcelain surface is critical in order to fire perfect porcelain, with the highest firing difficulty and the most perfect representative porcelain being full-glazed porcelain.
The full-glazed porcelain is a full-glazed porcelain in which the outer surface and the inner surface of the porcelain exposed outside are all fully paved with a glaze layer, and the firing difficulty of the porcelain is the highest, mainly because the porcelain impregnated with the glaze needs to be placed on a ceramic support before being fired in a kiln, and once the ceramic has a support point, the full glazing of the support part on the surface of the ceramic cannot be realized, so that the fired porcelain is not a full-glazed porcelain in the complete sense. The most common method in the art today is full-glaze firing, where porcelain is fired from late Tang. Because the glaze is melted at high temperature and becomes a semitransparent vitreous substance with high hardness after chemical change, if the glaze is fully coated and directly fired in a kiln, a vessel is stuck in the kiln to cause that the vessel cannot be taken down, so the bottom of the vessel in the prior art is not coated with the glaze. Later, in order to make the bottom glaze, the support pin was invented to solve the problem. The glaze is also adhered with the support pins, but the support pins have small areas, and the support pins are knocked down by things after being taken out of the kiln, so that the ware with the glaze filled at the bottom is usually marked with the support pins. Because the contact area between the tip of the nail and the porcelain is extremely small and is generally at the bottom of the porcelain and not easily perceived by people, the porcelain is gradually called as "full-glazed porcelain", but actually not full-glazed porcelain in the true sense. To achieve a complete full glaze, only two or more fires can be performed to mask the tack marks. However, the cost of repeated firing is extremely high and the yield is extremely low. In spite of the prior art in the field, no method can be used for firing complete full-glaze porcelain at one time, so that how to fire complete full-glaze porcelain at one time is an urgent problem to be solved.
Disclosure of Invention
In order to solve the problems in the background art and burn out complete full-glaze porcelain, the invention provides a full-glaze firing method for one-step molding of pot-shaped full-glaze porcelain.
The technical scheme of the invention is as follows: the full-glaze firing method for the one-step molding of the pot-type full-glaze porcelain comprises the following steps that a clamping seat is arranged on the inner edge of a pot opening of the pot-type porcelain, the clamping seat is an L-shaped seat body composed of a vertical wall and a horizontal wall, the clamping seat is integrally connected to the inner edge of the pot opening of the pot-type porcelain through the vertical wall and circumferentially extends along the inner edge of the pot opening, the horizontal wall of the clamping seat faces the center of the pot opening, and the full-glaze firing method comprises the following steps: the method comprises the steps of uniformly soaking glaze on the surface of the porcelain except for a clamping seat, taking a horizontal wall of the clamping seat as a circumferential supporting surface, reversely placing the porcelain soaked with the glaze and a supporting seat into a kiln for supporting and burning, wherein the supporting seat is a round table-shaped cylinder seat for supporting the porcelain, the top of the supporting seat is a large-caliber opening end, the bottom of the supporting seat is a small-caliber sealing end, and a convex part matched with the inner diameter of a kettle opening and used for supporting the horizontal wall is arranged on the outer edge of the circumference of the top of the supporting seat.
In the present invention, the width of the supporting surface of the tip of the projection is larger than the width of the horizontal wall.
Preferably, an adhesive is applied between the convex tip supporting surface and the horizontal wall.
According to the invention, the adhesive takes starch as a main material, and is prepared by sequentially adding 20-30% of diabase powder, 20-40% of aluminum powder, 6-8% of pseudo-boehmite powder and 90-110% of water into the starch, and then uniformly mixing and stirring, wherein the starch is one or more of white flour, corn flour, mung bean powder or sorghum powder, and the particle size of the diabase powder, the pseudo-boehmite powder and the aluminum powder is 80-120 meshes.
Preferably, the adhesive also contains allophane accounting for 3-5% of the total weight of the starch, and the particle size of the allophane is not more than 0.5 mm.
Preferably, the adhesive also contains 1-3% of alunite powder with the grain diameter of 80-120 meshes based on the total weight of the starch.
The pot-shaped porcelain in the invention is mainly a pot-shaped tea set which is commonly used in life, and also comprises other domestic or ornamental porcelain which is similar to the pot-shaped tea set porcelain in appearance.
Compared with the prior art, the invention has the following beneficial effects:
the method still adopts the idea of full-glaze firing, but on the basis of the traditional firing, a method of firing by a support pin is abandoned, the appearance characteristics of the pot-shaped porcelain are fully utilized, a clamping seat is arranged on the inner edge of the pot mouth of the pot-shaped porcelain, the clamping seat is used for firing and also serves as a base of a pot cover after firing, the pot cover matched with the pot-shaped porcelain is fired independently, and the finished pot cover is matched with the clamping seat to cover the pot mouth, so the clamping seat in the pot-shaped porcelain is not arranged independently for meeting the full-glaze firing.
Because the clamping seat in the pot-shaped porcelain does not need to be glazed, the horizontal wall of the clamping seat can be used as a supporting surface of the whole porcelain, and then the supporting seat with the supporting surface with the same size as the horizontal wall at the top is used as a support, the pot-shaped porcelain is inverted, the pot mouth faces downwards, the horizontal wall of the clamping seat is arranged on the convex part of the supporting seat in a sitting mode, and the pot-shaped porcelain can be placed in a kiln to finish the firing. In the method, the supporting parts are always positioned on the horizontal wall of the clamping seat before and after firing, and the glaze layer which is not contacted with the surface of the porcelain is not arranged, so that the fired porcelain is the complete full-glaze porcelain without supporting traces, and the complete full-glaze firing is realized.
In addition, because the center of gravity of the pot-shaped porcelain is not at the center, when the pot-shaped porcelain meets some large pot-shaped porcelain, in order to strengthen the binding force between the supporting seat and the pot-shaped porcelain and improve the stability of the porcelain support, the invention also provides an adhesive. The adhesive is used between the supporting surfaces of the supporting seat and the horizontal wall of the porcelain clamping seat, before the porcelain is fired in a kiln, a layer of adhesive is coated on the surface of the convex part of the supporting seat, the adhesive can be firmly adhered with the porcelain, after the firing is finished, the adhesive is only a thin layer, and the high-temperature dehydration in the kiln is thinner, so that the porcelain is very easy to separate from the supporting seat after being taken out of the kiln, and the influence on the porcelain is avoided.
In the adhesive, starch is used as a main material, and the adhesive has very high adhesiveness after being added with water and diluted at normal temperature, so that on one hand, the adhesive can meet the basic adhesive function, and the starch is solidified after being gelatinized at high temperature in a kiln and has very high brittleness, thereby facilitating the separation of porcelain and a supporting seat; on the other hand, in order to meet the requirement of environmental protection, the use of traditional organic ceramic adhesives such as resin adhesives, acrylic adhesives and the like is abandoned, and in addition, even if the resin adhesives, the acrylic adhesives and the like are used, after firing is completed, the adhesives are subjected to chemical combination reaction with the porcelain body and the supporting seat at high temperature, so that the separation of the porcelain and the supporting seat after being taken out of the kiln is difficult to realize;
besides starch, the pyroxene powder and the aluminum powder are used as core bonding components, as is well known, aluminum liquid obtained after the aluminum powder is melted at high temperature has extremely strong adhesion performance, the support seat and porcelain can be perfectly bonded and fixed, in addition, the pyroxene powder has high plasticity at high temperature, the starch is matched, the stiffness of the bonding agent is improved, the particle size of the pyroxene powder is extremely small, the total amount is not high, a cross-linking reaction with the porcelain cannot occur, the pseudo-boehmite powder is decomposed under the high-temperature roasting condition of more than 1000 ℃, nano-scale alpha-alumina, namely corundum, the particle size of the corundum is extremely small, the stability is high, the cross-linking reaction with the porcelain cannot occur, the starch is matched after the pseudoboehmite powder is discharged from a kiln, and the separation of the porcelain and the support seat is facilitated.
The allophane is porous loose structure, and it can form porous fluffy granule after the high temperature sintering, and partly aluminium powder and starch can improve the fragility of whole layer adhesive in the pore structure of allophane gradually under the high temperature, make things convenient for the separation of porcelain and supporting seat after going out of the kiln.
The preferably used alunite powder is decomposed at high temperature to generate alumina with extremely small particles, the hardness of the alumina is high, the strength and hardness of the whole adhesive are improved, and the phenomenon that the adhesive is brittle because of bearing large porcelain and is brittle in the kiln sintering process, so that the porcelain loses the center of gravity and collapses is avoided.
