The Stone Glassfire is probably the most universal of all Glassfire� models. The Scandinavian Stone base makes it a perfect choice for natural interiors of earthy colours and an ideal outdoor model for the patio, balcony, terrace or a sunroom. The Glassfires use a unique and environmentally friendly fuel called Fanola�, which is a specially formulated bio ethanol made from sustainable and renewable plant sources. While burning, Fanola produces only carbon dioxide and water vapour in similar proportions to exhaled human breath.
