Description

TECHNICAL FIELD The present invention relates to a method for applying a pattern to the surface of a glassware with colored lacquer, and in particular, the surface of glassware such as cups, wine glasses, and other general glass tableware is colored. It is a method of decorating glassware by utilizing the transparency of glassware by lacquering, and introducing the advantages of lacquer crafts, especially transparent lacquer, and increasing the added value of glassware. .

(Prior Art) Conventionally, there is a method of decorating a glassware by engraving, heating such as enameling or plating, foil placing, etc., but the surface of the glassware in the present invention is sandblasted and then colored lacquer is applied. There is no way to decorate with wiping lacquer.

Conventionally, there is a method of coating raw lacquer on the entire surface of the glassware without sandblasting the surface and decorating the glassware by baking at high temperature, but this method is transparent to the raw lacquer. Therefore, if this is lacquered on a glassware, it has the drawback of diminishing the transparency of the advantages of glass, and the process is complicated and labor-intensive, which increases the cost and makes it unsuitable as general glass tableware. There is a lack of information.

Also, there have been glassware with makie since ancient times, but the makie is opaque, and this method requires a lot of labor and cost and is not suitable for general use because of the high cost The reality is that they are being pushed out by products such as plating and foil processing.

(Problems to be solved by the invention) [A] Japanese lacquer ware made by traditional Japanese lacquer crafts, due to the emergence of new materials such as synthetic resins and the progress of their processing technology along with the change of lifestyle, At present, which is gradually declining from the lifestyle, the present inventor pays attention to the transparency and light-transmitting properties of transparent lacquer, and by wiping it onto a glassware and decorating it, We came up with the idea of developing lacquer glassware that is transparent and has a color tone unique to colored lacquer.

[B] However, in this development, (a) if the glassware is simply coated with lacquer, it will be delacquered over time, so the surface of the glassware will be roughened into a ground glass shape and subjected to so-called sandblasting. However, even if sand blasting is applied, the conventional lacquer method using raw lacquer, etc. not only prevents the lacquered part from passing light when it is applied. , As a daily tableware, there is a risk of de-lacquering, considering the degree of washing.

It was found that there are problems to be solved such as.

(Means for Solving Problems) Therefore, as a result of various studies, the present inventor transferred a desired pattern rough image to an arbitrary position on the surface of the glass container, and sandblasted the pattern rough image transfer portion, A transparent lacquer pattern with a color and luster peculiar to lacquer is revealed on the surface of the glassware by wiping lacquer, which is a mixture of transparent lacquer with an appropriate amount of lacquer pigment, and then drying and polishing. We have come up with a way to decorate.

However, the object of the present invention is to give various unique lacquer patterns by applying lacquer to the surface of the glassware by a rational and simple method to give a unique added value to the glassware at low cost. In particular, it is intended to contribute to the glassware industry and the lacquer crafts world by enhancing the familiarity with general glassware so that it can be provided at low cost as tableware for general household or business use.

(Operation) (a) In this invention, since the color lacquer is wiped and lacquered after sandblasting the pattern transfer image on the surface of the glassware, the color lacquer has adhesiveness and the sandblasting treatment. Due to the entire surface of the pattern lacquer is rough and uneven, no matter how many times it is wiped out, the lacquer remains in the uneven part, and with normal washing, the lacquer of the pattern part cannot be wiped off. Have.

In order to completely wipe it off, it must be washed off with a thinner or a turpentine, and otherwise, the lacquer of the pattern is completely maintained and manifested even if the color lacquer layer becomes thin.

(B) In this invention, the colored lacquer applied to the glassware is transparent lacquer with a transparent color, and the pattern lacquer part is transparent and has a function of transmitting light.

The thinner the colored lacquer layer, the better the transparency.

In addition, the colored lacquer becomes more transparent with the passage of time, so the lacquer pattern on the glass surface also has the effect of increasing its transparency and passing light well as the days pass.

(C) The pigment mixed with the colored lacquer has a coloring effect, and has the effect of making the color of the pattern lacquered on the glass surface clear.

Embodiment An embodiment of the present invention will be described with reference to the drawings.

The drawing (FIG. 1) shows an example of a product (cup) on which a lacquer pattern is applied by the method of the present invention.
Transfer the underprint of the desired pattern to any part of the surface (1 ') of the pattern, sandblast the pattern underprint transfer part (2,2'), and apply colored lacquer (a) and (b) on the upper surface. Apply with a lacquer brush, immediately wipe it up (so-called wiping lacquer), dry in a lacquer bath, polish with a compound, remove oil and fat with square powder or titanium white, and wash with water to finish glass On the surface (1 '), a lacquer pattern (3,3') of flowers, which is transparent and has a color and luster peculiar to colored lacquer, is revealed.

The details of the above sandblasting process and wiping lacquer process will be described.

[A] Sand blasting process Sand blasting process of the cup surface in the present invention (2)
Is performed only on the portion to which the draft of the pattern is transferred, and the process is generally applied by the conventional method described below.

[B] Wiping lacquer process Next, wiping lacquer is performed as follows.

First, stains on the surface of the cup, especially on the place where the sandblast treatment has been performed (the pattern-under-image transfer portion), are washed off cleanly with detergent or thinner.

At that time, if oil remains, it will be difficult to dry, so wash it carefully.

Preparation of colored lacquer On the other hand, a suitable amount of lacquer pigment (paint) is added to transparent lacquer with a high degree of transparency (wooden-colored lacquer, ash lacquer lacquer, luster lacquer lacquer, Akoro lacquer, etc.) ) Colored lacquer (a,
B) is mixed.

Coloring method (so-called color lacquer method) Apply colored lacquer (a) with a lacquer brush etc. to one colored area (sandblasted surface on which one pattern pattern is transferred) (2) and immediately cloth etc. Wipe the color lacquer (a) evenly with care so that the above color lacquer (a) does not adhere to other colored lacquer (b) colored areas (another sandblasted surface) (2 '). Then, when applying other colored lacquer (b), wipe it up in the same manner as when coloring the colored lacquer (a).

In addition, coloring can be performed by blurring. For example, by applying red and blue colored lacquer to the same place as appropriate, and wiping it up while blurring the boundary between the colors, blurring is achieved.

Lacquer drying Next, the cup (1) is put in a lacquer bath (a wooden closed cabinet type), and the lacquer of the lacquer pattern part (3,3 ') is dried.

Polishing (Finishing) Then, attach the compound to a cloth and polish it, then remove the oil and fat with square powder or titanium white to obtain a gloss, and then wash off the dirt with water mixed with some detergent and use a cloth. Completed by wiping.

(Effect of the invention) The present invention makes use of the characteristics of colored lacquer (transparent lacquer) and effectively applies it to glassware. By lacquering the surface of the glassware with colored lacquer, The transparency of lacquer and the color unique to lacquer have the effect of increasing the added value of glassware by revealing various artistic patterns on the glass surface without obstructing and reducing the transparency, which is an advantage of glassware. That is, in this invention, the lacquer surface of the glass surface is also transparent and allows light to pass through, and the manifested pattern exhibits the color and luster peculiar to colored lacquer, giving the glassware a bright, beautiful, yet calm quality. There is.

Further, in this invention, since the colored lacquer having adhesiveness is applied to the sandblasted surface to lacquer it, there is no possibility that the pattern will be removed by delacquer in the washing of daily use and it can withstand long-term use, and , Its material is hygienic.

Moreover, the decorating process in this invention is simpler, requires less labor and cost than other glassware decorating methods, and can be processed at low cost. It can be said that it is the most suitable as a decorating method, and by doing so, it can improve familiarity with general glass tableware and, in addition, contribute greatly to the glassware industry and the lacquer industry.
