The present invention relates to a process of production of metal-decorating material of various designs, without the use of any chemical substance, which is the cause of pollution. The process of the invention is applied for creating a design on a metal surface of any article, or the process of the invention is applied for producing a metal decorating material in order to use for decorating on a surface of any article.
BACKGROUND OF THE INVENTION
In the production of any article, apart from the consideration of their utility, the aesthetics must be taken into account as well. There are different methods of decoration and beautification, e.g. carving, enameling or decorating with valuable materials, etc.
In case of metal article, different methods can be used to make decoration. However, in case that the decoration must involve the etching on the metal surface, the chemical substance is often used. Yet, there is a disadvantage that mostly the chemical substance will cause pollution.


DETAILED DESCRIPTION OF THE INVENTION
The invention purports to a process of producing metal-decoration material, which causes no pollution to the environment and can be used both in industrial manner and handicrafts such that the purpose thereof is to create an aesthetic appearance of the articles.
The term “metal-decorating material” used hereinafter both in this description and in the claims will include decorating material which is made of metal and can be used to decorate article made of metal or any other material; or the process of the present invention can be used directly to decorate the surface of metal article.
The term “article” used herein means material or an article used dn daily-life activities. The article includes, but is not limited to, furniture, component of a weapons such as sword handle and sword sheath, purse, etc.
The process of producing metal-decorating material of the invention consists of the step of making a pollenlike holder on the base metal surface which forms the base of the piece of the decorating material or the body of the article being made of metal, and the step of setting the design-creating material on said base material surface by using said pollenlike holder in setting the design-creating material on the surface of said base metal.
The term “base metal” used hereinafter means a metal piece or plate used as a base for producing a decorating material by applying the process of the present invention to a surface of the base metal such that a design is created thereon. The base metal may be any shape as desired such as triangular, rectangular, etc., and it may be a flat plate or a curved plate according to the article as desired.
The term “pollenlike holder” used hereinafter means a holder by which a design creating material can set onto the base metal surface, through the so-called “pollen” formed by the process of the present invention applied to a plane of the base metal surface as described later such that grooved markers crossing each other in a shape of a flower pollen can be formed on the surface of the metal plate. The process of production of metal-decorating material of various designs can be accomplished without the use of a chemical substance.
The design-creating material may be any kind of materials, which will embellish said base metal. As an embodiment of the invention, it is preferable to use precious metal, according to the periodic table, as design-creating material, e.g., gold, silver, platinum, etc. In this case, it is appropriate to roll or draw such precious metal to become a small thin thread about the size of a hair thread with the diameter of around 17 to 181 micrometers. In case that the decorating-material plate is produced before making decoration of the surface of the article, the base metal plate should not be more than 1 millimeters thick, even though the thickness and the width of the precious metal as well as the thickness of the base metal plate are not a critical point.
The process of producing the pollenlike holder could be done by etching said base metal surface, without using any chemical substance, but using any tool that could cause marks on the surface, e.g., a chisel, etc. Here, machines or human labour directly, may be used depending on the fineness of the desired work-piece. Thus, the pollen is formed by a crossing point of grooved markers etched in various directions on the base metal surface.
As an embodiment of invention, etching is defined as making the pollenlike marks on the surface of the base metal in order to be able to hold the design-creating material. This can be executed in the way that such marks cut across in different directions along at least 4 directions of the geographic directions on a plane of said base metal plate, namely:
1. the 1st direction—from the north to the south, i.e. from the top of the base metal towards the bottom in the perpendicular line, or vice versa,
2. the 2nd direction—from the west to the east, i.e. from the left of the base metal towards the right in parallel line with the horizontal level, or vice versa,
3. the 3rd direction—from the north-east to the south-west, making an angle of 40-50 degrees to the line according to the 1st order above, or vice versa, and
4. the 4th direction From the northwest to the southeast, making an angle 40-50 degrees to the line according to the 1st order above, or vice versa.
However, said etching is not necessary be in the order as mentioned above, that is, any etching direction may be optionally selected to perform first.
As an embodiment of the invention, the etching may be operated each time in one direction or more, depending on the tools used. Likewise, the next etching may be operated in the same direction, the reverse direction, the opposite direction or the slanted direction with respect to the previous one. The operation may be at least for 4 times (directions) or more, up to 8 times (directions).
Thus, in one set of the etching, if the etchings are performed along the 1st - 4th directions as defined above without etching in a reverse direction, then there are etchings for 4 times or 4 directions such that one pollen marker is formed at a intersection point as desired. If a different size is needed, then additional set of the etching is performed in the 5th, 6th, 7th or 8th direction that may be the same direction, the reverse direction, the slanted direction or the parallel direction with respect to the previous direction depending upon the feature of the old one and the new one as desired.
There must be a lot of pollen markers on each of the base metal plate in such the way that the number of the etchings depend on the desired design created on said metal plate.
As an embodiment of the invention, the etching may be operated following the direction in order 1, 3, 4 and 2 as mentioned above respectively, or can be done reversely; or the etching operation may be opted to increase to 5 - 8 times or directions, following the order 3, 4, 1 and 2 or the reverse order.
In addition, by a characteristic of this invention, it is optional in each time or each direction of the etching operation, to apply different degrees of heavy or light force as desired, e.g. by the above-mentioned characteristic, the force put in the fifth etching may be lighter than that applied in the second one even though both are operated in the same direction. It's also optional to make a set operation, i.e., the force applied in the first round etching may be stronger than that used in the second round. Moreover, the etching may be operated in the same direction at the angle of equal degrees, or some different degrees. However, the different angles of about 1 - 5 degrees are appropriate; etching operation may be opted by using etching tool to make an angle of 70 - 120 degrees against the base metal surface; the more preferable is 80 - 100 degrees.
By a characteristic of the invention, the design creating material will be fixed on the surface of the base metal which is already etched into the pollenlike holder, in any design as desired, making the pollenlike holder be able to hold the design-creating material by using any process, e.g., use a setting tool. Additionally, the design-creating material may be fixed at the end of either times of the etching operation, as from the 4th time to the 8th time as desired.
As an embodiment of the invention, the opaque-area in the surface between decorating design may be punctured to become partly or entirely transparent space, by using any method, e.g., fretting or cutting off by any means or tool such as a chisel.
As an embodiment of the invention, the puncture may be done in the manner that the edge of such design stays in the right angle between both surfaces, in slanted angle, or in the way that the design follows one after another in orderly fashion.
As an embodiment of the invention, the process of this invention may be used to produce design decoration on both surfaces, either being the same design or not; or it can be done only on a single surface.
As an embodiment of the invention, metal-decoration material of this invention will consist of a piece of base metal that is etched to be pollenlike holder on the surface and the design-creating material held by such pollenlike holder. Accordingly, this pollenlike holder will function as a setter of the design-creating material, making it unmovable, without the use of any chemical substance. Thus, this will render economy and reduce pollution.
As an embodiment of the invention, metal-decoration material produced by using this process may be used to decorate article made of metal or any other materials, e.g., night pouch, photo frame, box, small casket, decorated gable end of royal or religious traditional Thai building, top roof of the junk, etc. Moreover, the process of this invention may be used to make the designs on the surface of any article as desired.
