In the Ming and Qing dynasties, Enamel also gained popularity under the name “Farang.” Ming dynasty due to the limitations of the production technology and craftsmanship, the colors and products were relatively simple. The volume and shape of enamel also range from small to large, from concise to complex, from pure ornamental to practical, and in the middle and late Qing dynasty, with the gradual maturity of production technology.
Traditional enamel handicrafts are made in different ways:
- Cloisonné Enamel – The copper wire is coiled out of the pattern, glued, and then filled with different various colors of enamel gaze until the glaze layer covered on the surface reaches its appropriate thickness.
2. Filled With Enamel – This process is similar to cloisonné except the decoration on the surface is formed by techniques such as carving, corrosion or stamping, and lastly baked at a high temperature.
3. Enamel Painting – In this process, a layer of opaque glaze is fired inside and outside the metal tire as the base and painting patterns are applied on the base according to the design pattern and then baked to high temperature.
In today’s technology, the production of enamel is different from before. Brightly colored paint and pigment are already easy to make for enamel badges. The main process flow of making modern enamel pins are as follows:
- Mold making: Making of molds depends on the drawing or design provided by the customer. Most of the current mold is machine engraved, adding a three-dimensional effect.
2. Embryo making: The engraved mold is used to press out the required copper embryos. Generally, for embryo making, copper and silver is used.
3. Applies enamel material: The enamel is prepared by enamel material in layers. It is baked in an oven at an elevated temperature.
4. Smoothing: A metallographic grinding wheel is used to smooth out the surface of the paint, so the metal frames are exposed, and the glaze is smooth.
5. Polishing: There are 2 parts of polishing, first is rough polishing and second one is fine polishing. Paraffin is added to make the surface delicate, polished, and smooth with a mirror like finish.
6. Electroplating: The polished product can now be electroplated after acid-washing. Electroplating can be gold-plated, nickel-plated, chrome-plated, and copper plated.
Enamel badges are the highest grade of badge making that are durable and can be stored for a long time without discoloration or oxidation. However, with the continuous improvement of technology, imitation enamel is produced which is also very similar to real enamel craft. One of the advantages of imitation enamel is that the price is more affordable.
