Q: I’ve just started working with platinum, and I know I need some extra eye protection from the hotter torch temperatures involved. Are those blue cobalt safety glasses the best ones to use?
A:Don’t use those cobalt blue glasses with platinum. They’ve been around for years, yes, but a standard green welder’s lens is far better protection. The problem is that the blue lens, though dark enough to make it possible to see what you’re doing, does not provide good protection from either infrared or ultraviolet, both of which can be present when working with platinum. They look nice, but they’re not safe for any but very occasional use with platinum.
