Titanium is a metal that changes color with high temperatures, so if it receives a lot of heat in direct fire and/or with nothing inside it, it can darken. If this happens, it is only an aesthetic change, not affecting its properties or its safety at all. It can be washed in the normal way, even in the dishwasher, although it is recommended to wash by hand, with a soft cloth and detergent. Titanium is a metal that generates a very light layer of almost negligible oxide, a kind of protective film for the metal, stable and absolutely non-toxic. If a titanium product is scratched with a sharp object or scouring pad, this outer layer is affected and a scratch can be seen. This layer of oxide is recreated in that area, although it is not visible to the naked eye, it is one of the characteristics of titanium in contact with air and reinforces its biocompatibility.
