Description

Glass blowing technology using glass panels {Glass blowing technology using Glass panels}

The present invention is an improvement of the conventional glass blowing method that has been in existence for the past 2000 years. It uses plate glass to make the same glass container and glass craft as the blowing method without blowing the glass like the blowing method. A method is disclosed.

Until now, the method of making glass containers by blowing has been called batch, or silica sand, which is a raw material of glass. soda. Place the lime in a glass melting furnace and raise it to 1500 degrees Celsius so that the batch is vitrified, then dip the glass into a blowing rod and blow it into the glory hole while removing it. The method of finishing was used while keeping the thickness constant.

This conventional method was developed by Ettect in the first century BC and has been unchanged for the past 2000 years.

This blowing method involves placing the glass raw material, i.e., silica sand, soda and lime, into the melting furnace and vitrifying it, then cutting the glass with the end of a long blowing pipe (blowing pipe) with a hole in the middle. Use a ball to make a round ball, blow it like a balloon, shape it into a glass container of the size you want to make, and then use a punch stick to move the container and put it in a Glory Hole. A glass container was created by completely shaping the container, then removing it from the punch stick and placing it in a slow cooling furnace.

The conventional method is to purchase the main raw material of glass, namely, silica sand, soda and lime, and put it in the melting furnace and heat it to 1550 degrees Celsius for at least 12 hours. They couldn't put out the fire until it had reached the end of its life, and only those who had been trained for years could make the glass containers they wanted.

In particular, the blowing method as described above had to consume a lot of facilities, technology and energy. First of all, in order to make a batch that can be called as a raw material of glass, various raw materials must be mixed, and the prepared raw material batch was put in a melting furnace, and it was inconvenient to operate at 1500 degrees Celsius or more for 365 days while consuming a lot of time and energy.

In addition, in order to make the glass container by dipping the molten glass with a blowing pipe, it is necessary to have a few years of skill to make a shape freely, and the manufacturing process takes a considerable time to produce a glass container of a certain thickness.

The present invention has been made to solve these problems in the prior art has the following purposes.

First, it is possible to save time and energy by making a glass container without blowing the glass like blowing method using plate glass that is already widely spread around us, and to provide a more effective glass elution container.

Secondly, there is no initial investment for the installation of the furnace, and there is no need to keep the glass furnace at a high temperature for 24 hours 365 days. It is in such a way.

Third, because the work process is reduced and simplified, and no skilled workmanship is needed for many years, even a beginner can easily make a glass container of a certain thickness.

1 is a manufacturing process of the container by the sheet glass blowing according to the present invention

Method for the present invention to achieve the above object, by using a plate glass that can be easily seen around us to draw a container of glass on the plate glass in the shape of a pulverized picture, then cutting the plate glass with a glass knife as shown Preheat the cut glass into the preheating furnace, preheat the end of the long iron bar to the gas fire, take out the red barred iron rod, sit in the chair and spin it around using a torch fire Dissolving the appropriate amount of plate glass rod at the end of the iron rod, and dangling the plate glass contained in the preheating furnace as the glass melted at the end of the iron rod, and putting the plate glass hanging at the end of the iron rod into the glory hole to work Heating to a glass deformation temperature to facilitate When the plate glass suspended at the end of a stick is heated to a temperature in the ease of operation and for holding a step shape by the tool, and the shape of the glass vessel is complete, characterized by carrying out the steps for loading a to slow cooling.

An embodiment of this invention is described as follows.

Example 1

[Plate glass cutting process]

Draw an open picture of the glass container you want to make on a plate glass (1) that is widely used in everyday life and can be easily obtained anywhere, and cut it with a glass knife (1-2). The thickness of the plate glass is also determined according to the size and shape of the glass container to be made.

[Plate glass preheating process]

Put the finished glass (1-3) in the preheating furnace (2) and slowly preheat to about 200 degrees Celsius.

[Steel Bar Heating Process and Rod Glass Melting Process]

The end of the iron bar (3) is heated to the gas fire (4) red, and when the iron bar (3) is heated red, the glass rod (5) prepared at the end of the iron bar (3) is melted and glued in an appropriate amount using the torch (6). .

[The process of attaching the preheated plate glass to the iron bar at the end]

Glass (3-1) melted on the end of the iron bar (3) lightly presses it onto the center of the plate glass (1-3) preheated in the preheating furnace (2) to cool the plate (1-3). -1) Take it out at the end.

[Window Glass Heating Process]

Place the glass plate (1-3) hanging on the end of the iron bar (3) into the glory hole (7) and rotate it until it is heated to a suitable temperature to deform the shape.

[Process to make shape from plate glass]

The plate glass (1-3) melts in the grooved hole (7) and deforms into various shapes. When heated properly, the plate glass (1-3) is taken out and sits on a work chair while the iron bar (3) whirls the tool (7). Use -1) to make the glass container (1-4) as you want. If the glass 1-4 cools down and becomes hard enough to change the shape of the glass as the tool 7-1, it is put back into the glory hole 7 and heated to the deformation temperature of the glass. After this, take it out and continue to make a shape (1-4).

[Slow cooling process]

The glass (1-3) hangs on the end of the iron bar (3-1), enters and exits the Gloryhole (7), and is shaped and finished (1-5). ) Scratches the glass container (1-5) attached to the bar with a hacksaw or a string of iron, and then gives a slight impact to the iron bar (3). The iron bar (3) and glass container (1-5) can be easily The separated and separated glass (1-5) is put in a slow cooling furnace (8) and cooled slowly.

As the blowing method does not melt the batch of glass material into the glass melting furnace, it saves facility investment cost and saves energy because the glass melting furnace does not have to be operated for 365 days. Unlike the method, it is possible to reduce the manufacturing process by making household crafts such as bowls using plate glass that has already been produced, and to save time, and there is no inconvenience in the process. Not only can it be made, but it also has the effect of freely making glass containers of a certain thickness, such as flat glass, unlike blowing.
