  • Blue spots showing through flash copper, heat treated A2.

    Otherwise perfect parts showing blue spots that were not seen prior to plate.
    After heat treat, parts are tumbled in ceramic for 1 hr, pickled for 3 minutes in ultrasonic cleaner before being tumbled for another hr. Parts appear almost the same shade as before heat treat after the double tumble process, but after barrel plating for 45 minutes some show the blue spots. If anyone can shed light on this, I will be very grateful.. If photos are needed, I will have to compress or degrade as they were taken with a microscope.
