Hand Blown Glass Art

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

I found some really neat oldies in an estate. But they were stored in a shed and have powder mold on them, from this damp OR Coast climate. Any ideas how to safely remove this from the glass ornies? These are old German thin glass ornaments. Maybe there’s no helping them? Any ideas?
