Stainless Steel Portable Fire Pit

What type of patina can I expect to see on a Corten Steel Fire Pit? The surface of each of our special Corten Steel fire pits is aged to look as though the product has been in the elements for about a month. Be advised that your new fire pit will have a "rust" layer of residue from the manufacturing process, so we recommend that you avoid touching or sitting on it in order to avoid blemishing the surface (or your clothes). This layer will disappear over a short period of time after it has been exposed to the outdoor elements.
