The flame is staring to go under the glass and turn the glass black.

Thanks.

Quite a few years ago I started collecting specific blown glass candle holders and oil lamps, they are tie dye in color and very thin glass. I have been unable to find anymore of them in many years and was wondering if anyone had any idea where to find some online so I can expand my collection. Here is the link to the only website I found, so you have a picture to go by. This exact style, but in any color http://www.werbeyondcandles.com/images/oil_lamp_red.jpg
most of them have stickers on the bottom that say "flame glow" if that helps at all
