    CORONA A COMPACT FORM OF FIBROUS GOLD Some practitioners prefer a compact form of fibrous gold, while many prefer a more ope form as found in Moss Fibre. Corona was prepared to meet the ideas of those who prefer the gold more compact. It possesses all the superb qualities of Moss Fibre in a form that for some uses is preferred by many who are familiar with both preparations and has found many users among those who have avoided other fibrous golds. It is a mass of irregularly interlaced filaments, brought so closely together as to present much the appearance of a felted gold. It is very plastic, therefore easy of adaptation to the walls of the cavity. It is pure gold, so treated that the maximum of cohesiveness is conserved, ready on the application of force, after proper annealing, to be welded into a solid mass. Because of the closeness of its fibers, a given bulk contains a considerably greater weight of gold than one of looser fiber. Each portion, through this compactness of structure, by so much hastens the completion of the filling. Condensation is easy and rapid because the fibers are laid up so closely to each other. Corona, like all golds of its general character, must be carried to the cavity in small portions, and each must be thoroughly condensed before another is added. So used, it makes a strong, resistant filling. In strips, for convenience in use. Put up in white enameled boxes, containing respec- tively -J and 1-40 oz.
