Description
Technical Field
The invention relates to the technical field of craft products, in particular to a production process of high and low temperature enamel metal ornaments.
Background
China is the home country of porcelain, the invention of porcelain is the great contribution of China to the world civilization, and the word "porcelain" in English has become the pronoun of "China". China is mature in porcelain and has professional institute and association. The Ming Dynasty cloisonne has a history of 600 years and is most accepted by Chinese people. Cloisonne enamel is named as 'copper body cloisonne enamel', also known as 'embedded enamel', and is a porcelain ware which is made by using soft flat copper wire to cloisonne on a copper body, and then filling enamel color glaze in the patterns and firing the enamel color glaze. The traditional cloisonne enamel uses silver body and copper body all the time, but rarely used for gold body. The cloisonne enamel is only suitable for appreciation in the palace in the Mingqing period, and does not consider the cost. The gold body cloisonne enamel has huge manual loss, can not be produced in standardized quantity, has high cost and is not beneficial to popularization.

Furthermore, the terms "first", "second", etc. are used for descriptive purposes only and are not to be construed as indicating or implying relative importance or implicitly indicating the number of technical features indicated. In the description of the present invention, "a plurality" means two or more unless specifically defined otherwise.
In this application, unless expressly stated or limited otherwise, the terms "mounted," "connected," "secured," and the like are to be construed broadly and can include, for example, fixed connections, removable connections, or integral parts; can be mechanically or electrically connected; either directly or indirectly through intervening media, either internally or in any other relationship. The specific meanings of the above terms in the present invention can be understood by those skilled in the art according to specific situations.
In this application, unless expressly stated or limited otherwise, the first feature "on" or "under" the second feature may be directly contacting the first and second features or indirectly contacting the first and second features through intervening media. Also, a first feature "on," "over," and "above" a second feature may be directly or diagonally above the second feature, or may simply indicate that the first feature is at a higher level than the second feature. A first feature being "under," "below," and "beneath" a second feature may be directly under or obliquely under the first feature, or may simply mean that the first feature is at a lesser elevation than the second feature.
Referring to fig. 1-2, a process for producing a high-low temperature enamel metallic decoration comprises the following steps:
s1: holding the metal blank;
s2: firing high-temperature enamel; the firing temperature is 800 ℃, and the error is +/-5 ℃; in order to avoid the oxidation of 9k gold, because the gold content of 9k gold is 37.5 percent, silver, copper and other trace metals account for 62.5 percent, and the metal ash is not melted and floats out of the metal surface to form a black oxide layer when the temperature is up to about 500 ℃, an atmosphere protection mesh belt type oven is adopted; the protective gas comprises 90 percent of nitrogen and 10 percent of hydrogen by volume percentage. The atmosphere protection mesh belt type oven has five temperature zones, wherein the first temperature zone is a preheating zone and the temperature is 200 ℃. The second temperature zone is a preheating zone at 500 ℃. The third temperature zone is a burning zone and the temperature is 800 ℃. The fourth temperature zone is a burning zone and the temperature is 800 ℃. The fifth temperature zone is a cooling zone, and the temperature is 300 ℃. Specifically, the enamel glaze is dripped into a position of the metal blank, which is correspondingly required to be glazed. Sequentially firing through five temperature zones.
The firing in step S2 is performed a plurality of times, specifically, a number of times of repeated firing is five or less, and when the firing is performed too much, the enamel cracks due to cumin, i.e., the metal cracks. Wherein the melting point of the 9k gold is 837 ℃, the melting point of the enamel is 750-. The firing time is therefore: 10-60s, the error of the firing time is within +/-1 s,
s3: polishing; primarily polishing the enamel and the metal blank.
S4: inlaying; the jewels, ornaments and the like to be embedded are embedded into the corresponding positions of the metal blank.
S5: baking the low-temperature enamel; (ii) a Dripping 100 deg.C low temperature glaze material into corresponding position of metal blank, baking at 100 deg.C, and cooling.
S6: secondary grinding;
s7: and polishing to obtain a finished product.
The high-temperature enamel process belongs to high-process products, and has a plurality of process limitations, such as structural problems of material hardness, large product amplitude curve, product thickness, enamel filling groove depth and the like, which are all reasons for influencing the success or failure of the high-temperature enamel. The low-temperature enamel does not need high temperature and is not limited by structures and materials, so that certain structures of the high-temperature enamel which cannot be formed. Enamel is most famous in france in europe and japan in asia.
Enamel is limited in development in China. There is no industry association, professional institute, etc. The transmission is carried out in a way that the master carries the brothers and the mouth and mouth. Enamel, a non-material cultural heritage, is facing the danger of being broken and lost. The product combining 9k gold and high-low temperature enamel is developed, the processes of light transmission, filling, micro drawing, wire inlay and the like are realized, the standardized mass production can be realized, and the propagation and inheritance of the non-material heritage of the enamel process are realized in the face of young consumers after 90 and 95. The cost of 9K gold is low, and the price is suitable for consumption of young people. Improved color binding is more acceptable to young people after high and low temperature enamel is combined with low temperature enamel.
Optionally, the metal blank is 18k gold, 9k gold or 925 silver.
Because the color of the high-temperature enamel has different presentation effects on different metal blanks, for example, the expressive force of blue-green system is better in yellow 9k, and the expressive forces of red and yellow are slightly worse, the color of the low-temperature enamel is used for making up the color defect of the high-temperature enamel on different metals.
In an alternative embodiment, if the metal blank is red 9k gold, then the blue and green colors are color supplemented with low temperature enamel.
In an alternative embodiment, if the metal blank is yellow 9k gold, the red color is supplemented with low temperature enamel.
In an alternative embodiment, if the metal blank is white 9k gold, the red color is supplemented with low temperature enamel.
Finally, it should be noted that: the above embodiments are only used to illustrate the technical solution of the present invention, and not to limit the same; while the invention has been described in detail and with reference to the foregoing embodiments, it will be understood by those skilled in the art that: the technical solutions described in the foregoing embodiments may still be modified, or some or all of the technical features may be equivalently replaced; such modifications and substitutions do not depart from the spirit and scope of the present invention, and they should be construed as being included in the following claims and description. In particular, the technical features mentioned in the embodiments can be combined in any way as long as there is no structural conflict. It is intended that the invention not be limited to the particular embodiments disclosed, but that the invention will include all embodiments falling within the scope of the appended claims.
