Oxidized Finish usually refers to a surface decoration that has undergone special treatment to obtain an oxidized appearance, rather than achieving it through natural rusting, During the process of oxidized finish, chemical oxidants, special coatings, or other means are often used to deliberately create an antique and oxidized appearance. This treatment can cause the metal surface to exhibit textures and colors similar to rust or natural oxidation, thereby creating a unique aesthetic effect. So, if you want to deliberately create an oxidized appearance on the iron surface, in addition to removing oil stains, you can use appropriate oxidants or special treatment coatings to achieve this goal. Through such treatment, you can obtain texture and color similar to Autoxidation on the iron surface without relying on natural oxidation process. That sounds like a beautifully designed and durable fire pit! The heavy-duty steel construction, aged oxidized rustic finish, and authentic rust patina certainly give it an antique look and character. The unique finish is formed through the exposure of metal to water and oxygen, creating a natural weathered appearance. 
The production process of creating an oxidized finish for an outdoor fire pit kit typically involves several steps. Here is a general overview of the process:
Surface Preparation: The first step is to prepare the surface of the fire pit kit. This involves cleaning the metal surface thoroughly to remove any dirt, oil, or protective coatings that may interfere with the oxidation process. Various cleaning methods such as sandblasting, wire brushing, or chemical cleaners may be used.
Application of Oxidizing Agent: Once the surface is clean, an oxidizing agent is applied to initiate the oxidation process. Common oxidizing agents used for this purpose include vinegar, hydrogen peroxide, and special oxidizing solutions available in the market. The oxidizing agent is typically sprayed or brushed onto the metal surface, ensuring an even application.
Exposure to Air and Water: After applying the oxidizing agent, the fire pit kit is exposed to air and water. The exposure allows oxygen and moisture to react with the metal, initiating the oxidation process. The duration of exposure can vary depending on the desired level of oxidation or the specific instructions provided by the manufacturer.
Repeated Applications: In some cases, multiple applications of the oxidizing agent may be necessary to achieve the desired level of oxidation. This step involves applying the oxidizing agent, followed by exposure to air and water, and repeating until the desired finish is achieved.
Sealing and Finishing: Once the desired level of oxidation is achieved, the fire pit kit may be sealed or finished to protect the surface and enhance the appearance. This step can involve applying a clear coat or protective sealant to prevent further oxidation and to provide a more consistent and durable finish.
It’s important to note that the specific production process may vary depending on the manufacturer and the desired outcome. It’s recommended to follow the instructions provided by the manufacturer to ensure proper application and maintenance of the oxidized finish on your outdoor fire pit kit.
