Powder Coating Cast Aluminum Limitations

We are developing a new product out of Cast Aluminum. It requires a finish that will withstand heat from a fire w/o harming the finish.If possible, the finish needs to appear as a "patina" or a layering of colors (example: to look like slate or stone). So far this is a concept. Until we know this can be accomplished in cast aluminum, I cannot proceed.
