Description

  The present invention seeks to finally obtain the number of glasses to be laminated and the heating or cooling temperature and required time in the process of change between solid and liquid when laminating and fusing a plurality of glass sheets. It depends on the form of the product. At this point, the point temperature is determined by observing the temperature process before dissolving one parent glass as a sample and measuring the temperature at the point where it changes from solid to liquid. By adjusting the degree of fusion to such an extent that the temperature will be spread evenly over the entire stack and maintain the stacked state at that point temperature, the upper and lower inner layers will be in a mosaic or combination Conventionally, it was possible to express only by painting, printing, or mixing with blown glass without adding cracks or distortion even when adding a pattern made of cut colored glass or heat resistant material The processing of lath and the production of mosaic glass, which uses a metal such as lead or tin as a sash, and joins dissimilar / unique glass, use the above-mentioned technique of applying a stained glass cutting technology and placing a pattern and heating it. By using a method that can be applied to the top, bottom, left and right of the laminate, it is possible to produce a living tool with originality and artistic art without using harmful substances such as lead.

Laminating the solid plate-shaped glass and integrating it by heating to adjust the desired shape is to secure the shape created by partially liquefying and fusing while maintaining the shape as a solid. It is based on the sampling point temperature data shown in [0001], which is different from the simple process of changing temperature from liquid glass to solid glass, in which the shaped work is blown up and the shaped work is cooled down to a solid state. In the process of both temperature rise and slow cooling, the entire laminated glass is guided and fused to the point of change to the liquid state without breaking the solid form of the glass layer, and in the fusion between different glasses It is essential to stabilize in a fusion environment on the verge of causing cracks or breakage due to the difference in expansion coefficient that normally occurs.
At this time, the minimum time required to secure a uniform temperature change in the rising temperature process and the upper limit of the heating temperature that keeps the shape to be finally created slightly differ depending on the quality of the material glass used and the number of laminations, The time required for the temperature rise and the temperature raised to the limit to be equalized was determined based on a thickness of 10 mm according to the number of layers to be stacked and classified into two types, that is, less than or greater than the thickness.
The fusion temperature due to the difference in vitreous quality is grasped in advance by sampling shown in [0001], and the temperature difference between the upper and lower parts of the laminated glass during heating is led to fusion while making it uniform. It is necessary to set a uniform temperature change at the time of slow cooling without losing the transparent feeling and to set and guide the temperature up to the limit temperature at which the slow cooling is completed. The rise and fall of the temperature when the temperature rises and falls requires a uniform temperature change inside the glass to be laminated, which depends on the number of laminated layers and the total thickness. Three points of change of fusion start temperature, solid shape maintenance temperature, and transparency maintenance temperature that differ depending on the quality of the material glass. Measures must be taken to maintain uniform temperature throughout the work at the contact temperature, by maintaining the respective contact temperatures for the same time. If the work breaks down, measures to equalize the temperature at the changing temperature that will be the contact point are performed by changing the thickness of the laminate.
The three-point changing contact temperatures of these various materials are as shown in [0001]. When a single piece of a parent glass of about 3 millimeters is used as a sample and examined with a simple baking oven, there are slight differences depending on the quality of the glass. However, the fusing start temperature is around 700 degrees Celsius, the solid shape maintaining temperature is around 800 degrees Celsius, the transparency maintaining temperature is around 500 degrees Celsius, and the maximum normal temperature at the end of slow cooling is around 350 degrees Celsius. It was discovered that.

When expressing a surface that requires changes such as a delicate curved surface or dent such as a colored dome surrounding dishes or dishes such as plates and bowls with a laminated glass, the number of plate glasses that are 3 mm thick is about 3 It was found that by limiting the thickness to about 10 millimeters, a good product in which the stacked layered forms were integrated by fusion could be manufactured.
First, an arbitrary design made of colored glass or heat-resistant paint is placed on the top and bottom of the laminated glass at a desirable position to give the work its original design. The method of heat fusing of works of 10 mm or less raises the temperature at the fusion start junction temperature of 700 degrees Celsius, where it is placed in this environment for about 30 minutes, and the glass is allowed to wait for the whole to adjust to the temperature. The temperature is raised up to about 800 ° C. to start melting, and it is left in this environment for about 10 minutes, and then the cooling is started after the whole is adapted. Perform rapid slow cooling until the transparent maintenance temperature is about 500 degrees Celsius, wait about 20 minutes for the whole to adapt to this environment, then slowly slow cooling to 350 degrees Celsius at the end of slow cooling. The firing is completed.
The relationship between the temperature change in this step and time is shown in the following graph.

When firing laminated glass with a thickness of more than about 10 mm, the thickness of the product gradually increases, so that uniform temperature rise to the inside of the work is taken slowly [0003] or more while preventing uneven firing and preventing the occurrence of uneven firing. It is necessary to make a product that has been transformed. Therefore, each time the thickness increases, it is necessary to heat and bake twice or three times at each stage, and a uniform temperature rise in the laminate according to the number of glasses to be fused is ensured. This can prevent cracks and the like due to the temperature difference between the surface and the inside. In this case, if the final maximum temperature at the time of a temperature rise of 10 mm or less is added, the fusion of the stacked glasses will proceed too much to maintain the entire shape, so that the maximum temperature is set to about 700 degrees Celsius below about 100 degrees Celsius. It becomes a work with a clear stacking situation throughout the minute.
First, an arbitrary design made of colored glass or heat-resistant paint is placed on the top and bottom of the laminated glass at a desirable position to give the work its original design.
The method of heat fusion of works exceeding 10 mm is started at around 700 degrees Celsius while trying to homogenize the temperature environment for about 30 minutes at every temperature rise of around 200 degrees Celsius in order to slowly familiarize the entire glass with heat. Raise the contact temperature, leave it for one hour in this environment, wait for the whole to adjust, then fuse only the laminated parts around the work to integrate it while maintaining the whole shape, and gradually cool down to go into. In the slow cooling process, considering the thickness of the work, the transparency maintenance temperature is divided into two stages up to around 500 degrees Celsius, and the environment is maintained at around 600 degrees Celsius for about 15 minutes by rapid slow cooling. After the temperature reaches about 500 degrees Celsius, the environment is maintained for about 30 minutes, and slow cooling is performed to 350 degrees Celsius at the end of the slow cooling, and thereafter the firing is completed.
Since the work obtained by this method increases in strength as the thickness increases, it can be used indoors and outdoors as a building material or interior.
The relationship between the temperature change in this step and time is shown in the following graph.

Using the reverse of the temperature difference between the surface of the laminated glass and the inside, it is possible to fuse only the surface, generate cracks inside and generate a crack pattern, this is a glaze applied to the ceramic surface seen in pottery works This is a method of generating a pattern in which a crack is intentionally generated in the above-mentioned glass inside the laminated glass. In this case, the method of generating cracks using the difference in expansion coefficient by shortening the time of temperature equalization in the firing step and the difference in expansion coefficient depending on the material by changing the material of the glass layer to be laminated are used. There is a method of artificially generating cracks.
