- Alsterfors experimented with new glass techniques and often used opal glass and bright colors, giving their products a unique character.
The factory became part of the AB Åfors group (later Kosta Boda) but closed in 1980 due to financial difficulties. Today, Alsterfors glass is sought after on the collectors' market, especially works by P O Ström.
