摘要： There is disclosed a method of making composite glass tubing, and a molten glass feeding apparatus uniquely designed to carry out such method. The feeder apparatus comprises concentrically-arranged cylindrical containers, a blow tube located within the central container, and a plug member mounted on the base of the blow tube. The bottom portion of each cylindrical wall is downwardly and inwardly directed to provide restricted annular bottom openings. The bottom edges of the cylindrical walls and of the plug are positioned in such relation to each other that orifices are provided through which annular streams of molten glass may flow and contact adjacent streams in the fluid state, thereby forming composite glass tubing having at least three layers.
