Kosta Boda, previously known as Kosta Glasbruk, is a Swedish glassmaking company founded by two foreign officers in Charles XII's army, Anders Koskull and Georg Bogislaus Staël von Holstein, in 1742.It is located in Kosta, Sweden. Early production consisted of window glass, chandeliers and drinking glasses. From the 1840s, the factory was at the forefront of new trends and technical developments, producing pressed glass, and in the 1880s setting up a new glass-cutting workshop. In 1903, the company merged with the Reijmyre glassworks but both retained their own names and Kosta went on to maintain its reputation as one of the leading Swedish manufacturers with a range of fine art glass and tableware by distinguished designers.

Anna Ehrner, born in 1948, has been associated with the firm since 1974. This bowl is from the ‘Contrast’ range and is made using a technique called centrifugation which creates trails of colour inside the glass body. While the design is still produced today, it is no longer available in this size and the lines here are more angular than those found in the modern examples, suggesting a dating to the late 1970s or 1980s soon after Ehrner began working for Kosta Boda.
