Scandinavian brutalist modern textured glass candle holder by Meri Lassi designed by Pertti Kallioinen. Called Tulivuori or Volcano, it is a candle holder for 5 tealights, handmade in Finland. Each piece is unique and designed with a different number of tea light holders, from 3 to 7 lights, and they all have the same look of peaks in a group of volcanoes.
The company started in 1982, but seems to have had a connection with another Finnish glass company, Muurla Lasi. which started in 1974 and is still in production.
