These types of pins are more durable and sturdy than soft enamel pins. A lot of people will choose this pin instead because it has a very clean look.
Hard enamel pins become filled with the color enamel after the image is stamped in and cut out. Each color is cured in the oven one at a time, which can add to the expense of this pin because it takes a lot more time.
The pin is then polished down to be smooth and flat with the metal die lines. Because the grinding process is crucial, not all metal finishes work with the hard enamel pins. Gold or silver metal plating are some common options that you may use with a hard enamel pin.
After the colors are added and the pin has been polished, it is electroplatedand polished one more time. This completes the pin.
The polishing process is done multiple times and it makes it a little harder to get specific detail in hard enamel, such as thin lines or small engravings.
