In an article for the Journal of American Conservation authors McNally and Buschini note that "the Glass Flowers are not made simply of glass. Many are painted (particularly models made in the years 1886–95) and varnished; some parts are glued together, and some of the models contain wire armatures within the glass stems. Coloring of the models ranges from paint to colored glass to enameling." [1] To this day, no one has been able to duplicate the Blaschka's fine artistry.
