THE EFFECTS OF FLUORESCENT LIGHT ON BLACK OXIDE FINISH

MY NAME IS CHAD BOGDAN, I WORK FOR A SHEETMETAL FABRICATOR IN WHITE BEAR LAKE MINNESOTA, MY QUESTION TO YOU IS.

OUR QUALITY MANAGER SAID SOMETHING THE OTHER DAY THAT JUST SOUNDED FAR FETCHED, HE SAID THAT FLUORESCENT LIGHTING CAN CAUSE THE BLACK OXIDE FINISH TO FADE OR DISCOLOR, IS THIS TRUE.

No, but water can turn it to red rust.
Your manager may be thinking of dyed anodized aluminum.

Rest in peace, Ken. Thank you for your hard work which the finishing world, and we at finishing.com, continue to benefit from.

Real black oxide on iron or steel is not sensitive to light.Hope it helps and good luck!
