ABSTRACT:
A filled tubular article includes an elongated metal conduit having a melting temperature above the temperature of a molten metal in which the article is immersed. A core having first and second different and discrete materials is located within the conduit, and the composition is such that the first material controllably treats the molten metal while the second material liquifies and accelerates the liquification of the internal surface of the conduit to promote rapid dissolution thereof.
