The Natural History Museum branch of the National Museum of Ireland in Dublin was among the Blaschkas' "earliest customers and initially commissioned 85 glass models, paying the then significant sum of £15. It went on to purchase 530 models from the Blaschkas" – making it the largest collection of Blaschka Invertebrate Models in Europe Since then, the Dead Zoo, as Ireland's Natural History Museum is sometimes called, "has undertaken research on the conservation of these delicate objects." Noteworthy in that, like Corning, they have forever taken excellent care of the Sea Creatures, the National Museum of Ireland is another center of learning regarding the Blaschkas; a fact proven in that, in 2006, they hosted (alongside University College Dublin) the Dublin Blaschka Congress, "conceived as a gathering to bring together the diverse scholarly disciplines that are uniquely, if eccentrically, joined in the study of scientific glass models." Crucially and naturally, the Congress dealt with the Glass Flowers no less than their older maritime cousins.
