するものである。(Prior Art) As shown in FIG. 3, glass products such as pots 20 having mandala patterns of a plurality of colors, plates, pots, etc. have a high design effect and are products that are deeply popular in the market. As a method for manufacturing glass products having these mandala patterns, a method called so-called artificial blowing is known. In this method, a glass product having a mandala pattern consisting of a plurality of colors is produced as a single item using a laminated base glass manufacturing method using a crucible.

く望まれていた。(Problems to be Solved by the Invention) However, the method of manufacturing glass products with a mandala pattern by artificial blowing has drawbacks such as difficulty in mass production and extremely high product costs. Therefore, there has been a strong desire to develop a method for manufacturing glass products with a mandala pattern consisting of multiple colors using an automatic molding machine.

転数で回転させることを特徴とするものである。(Means for Solving the Problems) The present invention provides a method for manufacturing glass products having a Yodara pattern consisting of a plurality of colors using an automatic molding machine that can solve these conventional drawbacks. In a method for manufacturing glass products, different types of color frits are applied to a plurality of starters arranged in a line in a direction perpendicular to the flow of glass substrates in a feeder, corresponding to each starter immediately before the starters. The present invention is characterized in that, at the same time as charging, each of the starters is rotated in a direction of rotation in which the frit is wound downward and at a rotation speed that does not cause the frit to spread over a wide range.
（作用） 次に本発明の作用につき説明する。(effect) Next, the operation of the present invention will be explained.
第１図は本発明の製造方法の実施に供せられるカラーフ

示すものである。FIG. 1 is a central vertical cross-sectional view of a color feeder (2) used for carrying out the manufacturing method of the present invention, and FIG. 2 is a plan view of FIG. 1.

よりカラーフリットが投入される。The glass substrate 2 melted in the furnace body (not shown) is guided into the feeder 1 and is passed through the frit feeder 4 just before the starter 3.
More color frit will be added.

ある。As shown in FIG. 2, the starters 3 are arranged in a line in a direction perpendicular to the flow of the glass substrate 2, and corresponding to the starters 3, the same number of frits containing different color frits are arranged. A charging machine 4 is similarly arranged. The frit input port 5 of the input device 4 is arranged so that the color frit is inputted immediately before the starter 3, and the distance from the color frit input position in Fig. 2 is within a distance range smaller than the maximum outer diameter length of the starter 3. It must be. Specifically, the maximum outer diameter length of the stirrer is D, and the star
Letting L be the distance from the 1-layer to the farthest end of the frit inlet, it is necessary that D>L.

常のカラーフィーダーと同様、流出量に対して０゜５〜
２．５重量％の範囲内で行なう。This is the result of analyzing the flow of the glass base near the starte, which is the entrainment flow S by the starte and the stirring flow T of the glass base.
This is because it is necessary to directly roll up the color frit and introduce it into the flow S in order to obtain a glass base having a mandala pattern. Therefore, if the distance of the color frit insertion position is outside this range, the desired mandala pattern will not be obtained. Also, the input amount of color frit is 0°5 to 0.5 to the outflow amount, similar to the normal color feeder.
It is carried out within the range of 2.5% by weight.

う欠点がある。On the other hand, the rotation direction of the starter 3 must be set so that the frit is rolled downward, and the rotation speed must be set so that the thrown frit does not spread over a wide range. is preferred. If the rotation direction is reversed, the entrainment flow S will move upward and the frit will not be able to be stirred due to the relationship between the start and the tit. Also, if the rotation speed is less than 0.5 rpi, there is a risk that the color frit will not be caught in the starte, and if the rotation speed is higher than forpm, air will be trapped in the glass substrate and bubbles will be generated, or the glass substrate will be stirred too much and the desired result will not be obtained. In some cases, a mandala pattern cannot be obtained. Note that the temperature of the molten glass base near the starch 3 is preferably 1150 to 1300°C. At temperatures below 1150°C, the color frit will not be sufficiently melted and will remain highly oxidizing, which may cause 02 bubbles to occur due to reaction with the glass substrate, which has low oxidizing properties.
Temperatures higher than 1300° C. have the disadvantage of causing problems in cooling the product after forming the glass product and further promoting damage to the feeder.
