Description

A stunning Scandinavian blue and lilac glass bird paperweight.  Made by FM Konstglas of Ronneby, Sweden. Signed to base FM, Ronneby, Sweden, B 860 - 140 and still bears the original factory label. Designed by Benito Marcolin, pattern number B860. Benito and his brother Josef founded FM Konstglas in 1961. The lilac layer is made from Neodymium glass (also known as Alexandrite glass), which changes colour according to different lighting conditions.  It appears lilac in natural sunlight or yellow artificial light, and smokey blue in fluorescent/white light (see pictures). This is due to the presence of Neodymium oxide (Nd²O³) in the glass.
