Soft enamel and hard enamel are two popular types of enamel used in the production of pins, badges, and other metal products.

The main difference between soft enamel and hard enamel is the process used to create them and the resulting finish.

Soft enamel is created by filling recessed areas of a metal object with enamel paint and then baking the object at a low temperature. This results in a slightly raised surface with a textured feel, where you can feel the metal ridges between the enamel. Soft enamel is more affordable than hard enamel, and it has a more rustic and handmade look to it. The enamel colors may be slightly muted compared to the hard enamel.

Hard enamel, also known as cloisonné, is created by filling recessed areas of a metal object with enamel paint, and then polishing the surface until it is flush with the metal. The object is then baked at a high temperature to create a smooth, durable finish. Hard enamel is more expensive and has a more refined look than soft enamel. The colors are brighter and more vibrant, and the surface is smooth to the touch.

In summary, soft enamel has a slightly raised, textured finish with more muted colors, while hard enamel has a smooth, flush finish with bright, vibrant colors.
