設定が大変むづかしいという欠点がある。(Prior Art and its Problems) As a method for producing enamel products having metallic luster, the following methods (1) to (2) are generally adopted. ■Metallic luster by raster ■Metallic luster by special glaze ■Method to obtain metallic luster using mica, etc. Method (2) generally involves applying a thin layer of luster made of metal resin salt after glazing and firing, and after drying, firing at a temperature of 500 to 700°C to obtain a metallic luster. Gold wire, which is usually applied to the edges of glass pots, etc., is made using this method, but this method cannot be finished at the normal enamel firing temperature, so the temperature is 500 to 700℃.
The disadvantage is that the temperature must be lowered to 100 degrees, and that the desired metallic luster cannot be achieved unless the raster is applied very evenly and evenly. Method (2) generally involves adding a large amount of MnO2 or FeO components to the frit component, and
This method attempts to obtain a glazed surface with metallic luster by firing at 0 to 850°C, but this method has the disadvantage that the coloration is limited to dark brown to brown because the main components are MnO2 and FeO. . Compared to the method of ■■, the method of ■ uses special additives such as pumice and mica in the glaze as a mill blend. You can spray it on the wet surface of the glaze by suspending powder of pumice, mica, etc. in water and spraying it on top of the wet surface of the glaze.
When fired, a large amount of gas is generated during firing, which leaves a significant amount of bubbles on the glazed surface after firing, making it impossible to obtain a smooth surface. For this reason, in JP-A-51-60211, when pumice and mica are used as auxiliary raw materials for enamel structures, the pumice, mica powder, etc. are made to protrude so as not to be completely buried in the glaze layer, and a large amount is generated during firing. This prevents defects caused by gases. However, this method also has the disadvantage that it is very difficult to set the firing conditions.
上述の如く、金属光沢を有するほうろうの製造は、未だ
工業的に安定した条件が確立されておらず、また、簡便
な製造法も確立されていない技術分野である。As mentioned above, the production of enamel with metallic luster is a technical field in which industrially stable conditions have not yet been established, nor has a simple production method been established.
（発明の目的）
本発明は、上述のような従来法の問題点を改善するもの
で、簡単な技術的手段によって、優れた金属光沢を有す

It is characterized by post-firing.

が薄板状であり、塗膜中に層状構造を作って配列された
該被覆薄板状粒子が光の多重反射を行う結果である。二
酸化チタン層及びフェライト層の厚さを調整することに
よって金属光沢の色調を変えることができる。Glaze can be applied directly to the base metal that has undergone normal pretreatment, or it can be applied to the base metal on which a glaze layer (fired layer or coated and dried layer) has been formed, then dried and fired. An enameled product with metallic luster is obtained. The reason why the metallic luster is obtained in the present invention is that the mica powder is in the form of a thin plate, and the coated thin plate-like particles arranged in a layered structure in the coating film perform multiple reflections of light. The color tone of the metallic luster can be changed by adjusting the thickness of the titanium dioxide layer and the ferrite layer.
以下に本発明を実施例によって具体的に説明する。The present invention will be specifically explained below using examples.
