Kaasa is a bioethanol working fireplace for the interior and exterior illumination from Iittala. The design was coined by the Finnish designer Ilkka Suppanem. Kaasa is made out of heat resistant glass and stainless steel by Iittala. Initially, Kaasa was an historical sea-sign (Baken), which stool along the Bothnia sea coast before. They were manufactured out of stone or wood and were similar to wooden piles of fireplaces before burning. Some Kaasas were sea signs for sailors, others marked good fishing areas, Sometimes there was fire set near Kaasas, to keep enemies away. At the end of the 19th century Kaasas lost their meaning and were replaced by lighthouses. Ilkka Suppanem created a new interpretation of these historical sea signs for the Finnish manufacturer Iittala. The word “Kaasa” comes from the Finnish concept “kasa” which means pile or bunch. More details: Kaasa is adapted to be used in rooms at normal temperatures (15 to 25 °C). It shouldn’t be used at places with direct sun income or near warmth sources. It has to be mounted so that no direct wind comes to it, e.g. In front of an open door or an open window. The room, where Kaasa is used in, shouldn’t have less than 25 m² of area or 60 m³ of volume and it has to be sufficiently aired. Kaasa shouldn’t be used as heater.
