Detailed Description

The application will be better explained by the following detailed description of the embodiments with reference to the drawings.

The application provides a hollow colored glaze frosted grape cluster which comprises a main stalk, a plurality of grape ears burnt and fused on the main stalk, wherein each grape ear comprises a secondary stalk and a plurality of grape balls, and the grape balls are burnt and fused on the secondary stalk through branch stalks respectively. The main stem, the secondary stem, the branch stem and the grape balls are all made of colored glaze, and are particularly soda-lime glass.

The grape ball is sequentially transparent colored glaze, white colored glaze and dark purple colored glaze from inside to outside, and the surface of the grape ball is provided with white frost which is partially fused with the colored glaze on the surface of the grape ball. The grape ball is provided with a connecting hole, part of the connecting hole is connected with the branch by burning and melting, and the other part of the connecting hole enables the grape ball to be communicated with the outside, so that stress in the grape ball is released, and the grape ball is prevented from being burst.

The dark purple colored glaze in the application may be black in visual sense, and is specifically obtained by adding a colorant such as manganese dioxide to the colored glaze.

The white cream used in the application is any one of rare earth long-acting noctilucent powder, talcum powder or reflecting powder. Specifically, the rare earth long-acting noctilucent powder is prepared by firing a mixture of strontium carbonate, aluminum oxide, europium oxide, dysprosium oxide and boric acid at 1400 ℃, mechanically crushing and grinding the mixture into powder, and sieving the powder with a 150-mesh sieve. Talc powder is magnesium silicate mineral, and is mechanically crushed and ground into 400-450 mesh powder. The reflective powder is prepared from silicon dioxide, calcium oxide, sodium oxide, titanium dioxide and barium oxide by mechanically crushing and grinding into 400-450 mesh powder.

As shown in fig. 1-9, the application also provides a method for manufacturing the hollow colored glaze frosted grape cluster, which comprises the following steps:

s1, preparing materials: taking transparent glass material 2 in a molten state by using a blowing rod sleeve, and blowing the transparent glass material into bubbles; then sequentially sleeving a white colored glaze material 3 in a molten state and a dark purple colored glaze material 4 in a molten state, and pulling Cheng Kongxin colored glaze pipe 1 by the sleeved colored glaze material to serve as a standby, wherein the specific structure of the hollow colored glaze pipe 1 is shown by referring to figures 1-2. In the process of sleeving the colored glaze materials with different colors, the viscosity of the white glass and the viscosity of the dark purple glass are lower, the transparent colored glaze materials are difficult to directly sleeve and form, and the viscosity of the transparent colored glaze is higher, so that the transparent colored glaze materials are firstly sleeved in the step, then blown into glass bubbles to play a role in shaping, the transparent colored glaze materials are used as supports for the white colored glaze materials and the dark purple colored glaze materials, then the white colored glaze materials and the dark purple colored glaze materials with lower viscosity wrap the outer sides of the transparent colored glaze materials respectively, and then the transparent colored glaze materials are rapidly drawn into a hollow colored glaze pipe with 3 layers and one body, wherein the diameter of the hollow colored glaze pipe is 10-15mm, before the colored glaze materials are hardened.

According to the application, the white colored glaze is directly used for mixing colors of colored glaze, and is used as a substrate by overlapping the white colored glaze and the dark purple colored glaze, and the white colored glaze is not transparent, so that the obtained grape ball has a relatively real color, and the grape ball is prevented from being transparent. The dark purple colored glaze after sleeving has a certain thickness and volume, so that the dark purple colored glaze has a darker color, and after the dark purple colored glaze is blown and the thickness is gradually thinned to form grape balls, the dark purple colored glaze can finally have purple color close to real grape particles, so that the coloring step is omitted. In addition, the colored glaze has glossiness and avoids the step of waxing.

It should be noted that the purple degree of different grape balls in the same grape string may be different, so the application can also adjust the thickness of the dark purple colored glaze material and the white colored glaze material in different hollow colored glaze pipes, so that the similarity between the colored glaze grape string and the real grape is higher.

S2, wire drawing: and (3) heating one end of the hollow colored glaze pipe obtained in the step (S1) to 750-850 ℃ by using a lamper flame spray gun with the flame temperature of 950-1100 ℃, pulling out the first tubule 5 after the hollow colored glaze pipe is softened, and then heating the hollow colored glaze pipe with a certain length to be softened by taking the joint of the first tubule 5 and the hollow colored glaze pipe 1 as a starting point, and pulling out the second tubule 6 to obtain a blowing piece. As shown in fig. 3a, the middle part of the blow molding is a blowing bubble 7, and two ends of the blowing bubble 7 are respectively connected with the first tubule 5 and the second tubule 6 into a whole.

S3, blowing: as shown in fig. 3b, the end of one of the first tubule or the second tubule is melted and sealed to form a sealed end 13, and the other is kept open. Then, the first tubule and the second tubule are respectively held by both hands, after the blown bubble 7 is burned to be orange, the blown bubble is blown into the blown bubble through the first tubule or the second tubule with holes, the first tubule and the second tubule are rotated by both hands, so that the blown part is in a rotating state, after the volume of the blown bubble is increased and the purple grape ball shown in fig. 4 is formed, the blown is stopped, and one of the first tubule or the second tubule which is melted and blocked is taken down, so that the preliminary grape ball shown in fig. 5 is obtained.

In the step S2 and the step S3, the purpose of drawing the first tubule and the second tubule is to make the operation of the process of blowing the grape balls simpler and to improve the completion efficiency and the yield. In the prior art, the blowing bubble has only one blowing rod, and the colored glaze is easy to droop and deform in the blowing process in the blowing bubble, which is an important reason that the grape balls are difficult to manufacture, the shapes are difficult to control and the yield is low in the prior art. According to the application, the tubules are respectively drawn at the two ends of the blowing bubble, so that an operator can conveniently hold the two tubules by hands respectively, and after blowing the blowing bubble, the blowing part can be rotated by manually rotating the tubules, so that the distance between the central axis of the grape ball body and the straight line where the first tubule and the second tubule are positioned is smaller than 1.5mm, and the shape of the obtained grape ball is ensured to be better. Therefore, the first tubule and the second tubule can ensure that the shape of the filled grape balls is obtained after the grape balls are blown, the positions of the central axes of the grape balls are overlapped with the straight lines of the two thin rods as much as possible, meanwhile, the difficulty of blowing the grape balls is reduced, the blowing speed is improved, and the dependence on the proficiency of operators in the process of blowing the grape balls is reduced.

Melting and plugging one end of the tubule is an important step of blowing, and if the first tubule and the second tubule are not plugged, the shape of the colored glaze grape is difficult to blow out under the condition that the first tubule and the second tubule are ventilated.

S4, frosting: the grape ball part in the preliminary grape ball is placed on a flame spray gun for preheating, so that the grape ball part is heated uniformly to 120-150 ℃, and the temperature can lead the white frost and the grape ball surface to be partially fused, thereby improving the adhesive force of the white frost. After heating, putting the grape ball part into white frost powder for rolling for one circle, taking out, heating the grape ball part again to uniformly heat the grape ball part to 100-120 ℃, and carrying out secondary heating for strengthening fusion between the grape ball and the white frost, so as to further improve the bonding firmness degree of the white frost and the grape ball and finish frosting. It should be noted that, the frosting operation may be performed multiple times according to actual situations, until the white frost on the surface of the grape ball meets the standards in terms of appearance and adhesion. When the first heating is performed before frosting, white frost is difficult to adhere to the surface of the grape balls when the heating temperature is too low and lower than 120 ℃, and when the heating temperature is too high and higher than 150 ℃, a large amount of white frost is adhered to the surface of the grape balls, so that the grape balls are difficult to show a real frosting effect due to excessive white frost, and in addition, the grape balls are softened and deformed at an excessive temperature. If the temperature of the second heating is too low, the fusion strengthening effect between the grape balls and the white frost is reduced when the temperature is lower than 100 ℃.

In addition, in the above step S3, the reasons why the closed tubule is removed after the blowing is completed include two aspects:

firstly, after removing one end of the tubule and plugging the position of the tubule with forceps, the grape ball may slightly deform, and at this time, the grape ball needs to be heated again, and blown into the grape ball through the tubule with the opening, so as to perform shaping, so as to keep the shape of the grape ball round and full. If the tubule with the opening is removed, the grape ball cannot be molded.

Secondly, if the perforated tubule is removed, the interior of the grape ball is vacuumized in a short time, and the grape ball is still at a higher temperature at this time, so that the grape ball is likely to break during the cooling shrinkage process, and the grape ball with a vacuum structure is avoided.

S5, annealing: as shown in fig. 6a and 6b, one of the first tubule or the second tubule, which is provided with openings, is removed and a connecting hole 10 is left in the grape ball 8. As shown in fig. 7, the stem 9 of the green hollow colored glaze material and the connection hole 10 are partially connected by burning and melting, and then the grape ball with the stem 9 is put into a annealing furnace for annealing. In this step, stress is already generated in the glass during the heating process, so that even after the grape balls and the branches are in fusion connection, the connection holes 10 are required to be ensured to be communicated with the outside, so that the grape balls are prevented from forming a complete closed structure, the stress is released during the annealing process, and the grape balls are prevented from cracking under the influence of the stress.

S6, forming strings: after annealing, a plurality of branch stems are connected with secondary stems 11 made of green hollow colored glaze material through burning and melting to form grape ears shown in fig. 8, and then a plurality of secondary stems are connected with main stems 12 made of green hollow colored glaze material through burning and melting to obtain grape clusters shown in fig. 9. Besides white frost, other structures of the grape strings are colored glaze products, and the bonding strength is high.

Preferably, in step S1, the transparent glass material, the white glass material and the dark purple glass material are melted at 1250-1350 ℃ for 18 hours, respectively, so that the transparent glass material, the white glass material and the dark purple glass material reach a syrup form.

In order to facilitate the operator to hold the first tubule and the second tubule in the blowing member and ensure smooth blowing, in step S2, the diameter of the first tubule is preferably 1.5-2.5mm, the length is preferably 90-120 mm, and likewise, the diameter of the second tubule is preferably 1.5-2.5mm, and the length is preferably 90-120 mm. After the first tubule is pulled out, the hollow glass tube with the length of 12-17mm is heated to soften by taking the joint of the first tubule and the hollow glass tube as a starting point, and the color and the size of the grape balls are ensured to be relatively close to those of real grapes within the length range.

Preferably, in step S5, the annealing temperature is 350-420 ℃, and the annealing time is 24-72h.

In the step S6, the diameter of the secondary stem is 5-6mm, and the length is 35-40mm; the diameter of the main stem is 8-9mm, and the length is 200-210mm. Each spike of grape spike comprises 3-5 grape balls, and each string of grape strings comprises 10-12 spike of grape spikes.

Preferably, the application also improves the white cream component, specifically, in the step S4, the white cream powder is any one of rare earth long-acting noctilucent powder, talcum powder or reflecting powder, and through researches, the three white creams are considered to have components similar to glass at present, and the three white creams can be chemically combined with the glass of the grape ball at high temperature, so that the white cream is firm and is not easy to fall off. However, the white frost obtained after coloring and waxing is easy to fall off along with the pigment and paraffin along with touching. The specific composition and particle size of the white cream have been described above and will not be described in detail.

In this embodiment, the main stem, the secondary stem and the branch stem may be sleeved with green colored glaze to obtain a green solid rod, and then one end of the obtained green solid rod is heated by a flame spray gun until the end is softened, and the corresponding diameters and lengths of the main stem, the secondary stem and the branch stem are pulled out. Wherein the preparation of the branch stems only needs to be completed before the annealing in the step S5, and the preparation of the secondary stems and the main stems only needs to be completed before the stringing in the step S6.

S2: and (3) wiredrawing: the flame temperature of a flame spray gun of a lamp worker is kept at 1100 ℃, the tail end of a hollow colored glaze pipe with the diameter of 10mm is heated to about 800 ℃, the hollow colored glaze pipe is softened, after the degree of stretching is met, a first tubule with the diameter of about 2.5mm and the length of about 110mm is rapidly stretched, then a region with the length of about 15mm on one side of the hollow colored glaze pipe is used as a blowing bubble to be heated and softened, and a second tubule with the diameter of 2.5mm and the length of 110mm is also rapidly stretched.

S6, forming strings: after annealing, 3 branches are connected with secondary branches with the diameter of 5mm and the length of 35mm through burning and melting to form grape ears, and then 12 secondary branches are connected with a primary stem with the diameter of 9mm and the length of 210mm through burning and melting to obtain grape clusters.

The talcum powder in the step S4 is magnesium silicate mineral (Mg ₃ [Si ₄ O ₁₀ ](OH) ₂ ) Mechanically crushing and grinding into 400-450 mesh powder for later use.

The colored glaze grape strings obtained in the embodiment 1, the embodiment 2 and the embodiment 3 are all real and vivid, the white frost effect on the colored glaze grape strings is relatively similar to that on real grapes, the colored glaze grape strings are not dropped in the processes of long-time placement and multiple touches, and the bonding force between the colored glaze grape strings and the grape balls is relatively good.

The ceramic white materials in examples 1, 2 and 3 are white colored glaze materials, and the "ceramic black material" actually refers to dark purple colored glaze, but the colored glaze materials themselves have a certain thickness and volume, and are observed to be relatively close to black by naked eyes, so that the colored glaze materials are called as "ceramic black materials" according to the habit.

The above embodiments are only for explaining the present application and do not limit the scope of protection of the present application, and those skilled in the art make various variations or modifications within the scope of the claims, which fall within the essential content of the present application.
