Tmo Sapeneva 1926-2006 was a post war celebrated designer from Finland. This piece is a triangle shaped candle stick holder with floating controlled bubbles in the middle of the glass. It's heavy. There are some folds in the glass from production and there is a large bubble near the bottom that at first glance looks like a chunk missing but it's smooth on the outside and it appears to be from production as well. There are no chips or cracks, please inspect the photos. The piece does not glow but I did take a photo with the back light so you can better see the bubbles.
