Science has come so far in the past few hundred years. At one time, designs would all have to be cut or melted into products and parts. Then, in the middle ages, European craftsmen discovered the patterns could be created in their armor by applying acids or chemicals to the products. While it may have appeared as a sort of magic at first, the process has now been further developed today and is becoming a regular occurrence in many industries. It is used by both artists and manufacturers alike, bringing decoration and embellishments to all sorts of products.

While armor designs are one use of this process, it can also be used for coins, plaques, circuit boards, stencils and a variety of other items. The process can be applied to nearly any metal, often steel, brass, nickel, copper and others are used. In addition, the process can be used on almost all types of glass as well. It is a much more cost effective process for molding and designing items. This is because mechanical machines and tools for designing metals can be very costly, and these processes require no mechanical work. It is also able to be accomplished much more quickly than traditional cutting and shaping methods.

Chemical etching is a useful procedure, but at the same time, it is a very specialized field. There are numerous steps that go into the etching process, and it takes delicate and careful handling to make sure everything goes along as planned. Knowledge of the various chemicals and acids, and knowledge of their reactions when paired with different metals is vital. Different metals will require different acids when being processed. Improper use of these chemicals can be very hazardous to the person using them and others nearby, so close attention and monitoring by skilled individuals should always be applied.
