Descripción
A crystal clear, resinous exudate from the Canadian balsam fir, Abies balsamea, native to northeastern North America. Canada balsam was introduced in Europe in the 18th century. It was used for as varnish, but was found to bloom in moist conditions and darken with age. It is currently used to permanently mount microscopy specimens and as an adhesive for optical lenses. Its softening point is slightly above room temperature.
