Under both longwave and shortwave UV light, dark orange streaks are visible on the lower parts of the stalks. This is a resin, probably the same one that was used to glue the stalks to the base. The streaks contrast with the rest of the stalks, which were not painted with a coating like most of the glass on many other Blaschka models.
