    This red mark may have happened during my "flare" incident or it may have been there all along, I don't know.

    Anyway to get rid of it?

    Its not a big deal and really hardly noticeable but just to make it perfect....

    Put dish washing soap to moist rough surface pad and rub that stain away. Use pad that is made of plastic material so it will not cause scratches to the glass. (Same type pads are used to clean dirty frying/oven pans.)

    Hi, my experience with some of the "red" glass stains is that it's not possible to remove it. I think the red is etched into the glass itself caused by overheating.

    I've polished out very light scratches from glass using very fine abraisive cloth followed by a light buff with fine metal polish on a cotton buff in a dremmel tool. However the abraisive has to be very fine, preferably in the region of 10,000 or better still 12,000 grit, which is essentially a metal polishing cloth. The best brand I have found is called 'Micromesh' but its not always easy to find. I would however be careful about reducing the thickness of the glass by any significant amount, given that it gets heated then cooled during each use-cycle... Test on a scrap globe first though!

    Very fine diamond, aluminum oxide or carborundum grinding paste...

    It will remove some glass but hopefully only the very surface will be discoloured.

    Red stained glass is not all that common but I guess most of us old timers have seen a few examples. I have seen Tilley onion globes nearly half red at the top half. Not sure but I think it may have something to do with a reaction to the heat and chemicals in the mantles. Almost certainly always on lamps that have seen sustained long term use. Never been able to remove it although I must admit I have never tried very hard. ::Neil::

    On ebay these glasses are usually sold as "rare with a lovely cranberry tint." :lol: :lol: :lol:

    Thanks. I hear you on the fine abrasive and lite rubbing. I'll post a pic when I get around to it. Rainy days are good lamp fettling days.

    I handled my second flareup like a pro. Discharged the air and waited for the flames to almost burn out. Tightened her up again and pushed some air in and she started right up.

    I like these little lamps.
