Some customers may decide to paint their fire pits with a high heat paint, which is available in several color options. So even though the surface may look rusty, the Fire Bowl will not rust through, warp or rot out over time. This weathering/patina process occurs at the surface level and the Patina finish helps to act as a coating, protecting the metal underneath from material degradation. All Fire Pits and their accessory products are constructed out of the same high carbon-grade steel and will eventually look similar with time and use. Because the amount of direct exposure to these natural elements may vary on specific parts of the product(s), some areas may or may not weather/patina as fast as others. The patina process usually starts off orange-ish in color, but will become more dark brown in appearance as the steel is continually exposed to water and heat. rain, moisture, humidity) and oxygen comes in contact with the iron in the untreated " Natural Steel Finish". This weathering/patina process is a completely natural reaction that occurs when water (i.e. No protective coating or finish is applied to the steel to preserve it from weathering or beginning to form its natural iron oxide patina (otherwise known as rust).
Usually this " Natural Steel Finish" appears gray or silver, but this too may vary based on the batch of sourced raw steel material used. This finish is simply the uncoated mill finish of the steel after it is formed at the mill. Many of our products start out in a state that we refer to as a " Natural Steel Finish". Patina can be seen as a decay-prevention method that materials themselves can implement.What is Patina? In metal, Patina is the finish that develops on the metal’s surface over a period of time due to a natural weathering and oxidation process. Archaeologists' studies show that patinas can protect a material from the agents of weathering for up to a century before the object becomes fully decayed. The most common form of patina is that which is found on the surface of coins, especially after subjected to the agents of weathering. Accumulated patina on the surface of objects can sometimes cause poor electricity conduction as well as electrical shocks. From the chemical point of view, the coatings of the materials such as oxides, sulfides, carbonates, and other elements in the coatings of the materials react with the weathering agents such as acid, oxygen, rain, sulfur-bearing compounds, and carbon dioxides to produce the resulting patina. Patina is a form of rust, which can be written as Fe2O3.nH2O. BRONZE F/X Instantly Produces a Dark, Brown/Black ‘Oil-Rubbed’ Bronze Patina on Mild Steel Without Using Oil OR Heat. Materials form patina to protect themselves against damage by corrosion, but can also be used for aesthetic appeal. Patina also forms as a result of old age, wear, or even polishing. Once a material is subjected to agents of weathering such as water, wind, ice, extreme temperature or other agents, it begins to undergo the oxidation process that ultimately leads to tarnish on its coat or surface. Patina results as a process of oxidation, weathering or both.
