According to this vid's descrip: "A demonstration of reverse glass painting inside a perfume bottle. The video was taken on a cruise down the Yangtze on the riverboat Victoria Queen."
Soothing experience to watch this art in execution. Does anyone know if such a bottle can even hold perfume? Nifty keepsake for someone at least.
In a world where 6 million people are added each month, every landscape matters.
Quarry, it looks to me like he was using water-based paints, so I think it would not be safe for perfume. I have some Christmas ornaments that were painted in a similar way through a hole in the glass ball.
