GC Corporation The GC Corporation, founded in Tokyo, Japan in 1921 and now one of the world’s largest manufacturers and suppliers of dental products, established its UK division (GC UK Ltd) in 1993, selling the then newly launched Fuji II light-cured glassionomer restorative material. GC UK Ltd grew quickly. It now provides a full range of GC Corporation chairside products. Laboratory products include investments, dental stones and composite and ceramic crown and bridge materials. The GC Corporation has had at least three ties (21599.1– condition, worn; 21599.2 – condition, worn; 20374.1 – condition, good, with tie 21599.2 being of a very similar design to the latest International College of Dentists European section tie – see below). There was a matching scarf to tie for women.
