Pamela,
Look at the photo attached.
This coating can be bright or matte black. It stands high-pressure sterilization. This is color anodizing process in eco-friendly solutions without chrome. Different colors can be obtained. If you want to conduct rust tests, give us a call, and I will send you a sample.
