Hello friends, Does anyone know a simple, safe, and inexpensive method to permanently darken stainless steel?
I'm involved in a project to create a vertical decliner (48 inches wide by 30 inches high by 1 inch thick cast concrete) sundial for our town's Municipal Center showing hours until sunset. For the hour lines we intend to use 1/4 inch square stainless steel bars imbedded into the concrete. Test castings show that, when sunlit, the imbedded bars appear dark from most viewing angles, but that from some angles reflect light so as to almost disappear. Although the changing appearance of the hour lines might be considered a positive feature, I'd rather the hour lines always looked dark. Thanks for any suggestions.
