Despite criticism and early technical failures, the taming of liquid hydrogen proved to be one of NASA's most significant technical accomplishments. . . . Hydrogen -- a light and extremely powerful rocket propellant -- has the lowest molecular weight of any known substance and burns with extreme intensity (5,500Â°F).
The Solar Eclipse/Welding Glasses offered at myeyewear2go are ideally suited to any task or situation that involves eye-damaging light, including welding, solar eclipse viewing, and the viewing of direct sunlight. The green athermal shade 14 glass lenses utilized in these frames block over 99% of UV light and 97% of Infrared Radiation.
For gas cutting, welding, or brazing, the intensity of the light is much less than from arc welding, cutting or gouging processes. Lighter shade filter lenses can be used with goggles in place of a helmet. More information can be found in the OSH Answers on Safety glasses and face protectors.
