Producing Solder Glass Canes

An application for drawing solder glass canes is provided, whereby control of the diameter of the drawn cane is simplified.

The apparatus for producing solder glass rods of different diameters includes a container 2 which is cup-shaped to hold the solder glass melt 4. One end of a feeder tube 6 is connected to a bottom opening in the container 2 and the other end of that feeder tube is opened. A rod 8 is inserted through the feeder tube 6. When the glass melt flows from the container 2 and through the feeder tube 6, the rod 8 serves to drag and slow down the flow of the molten glass 4 as it comes out of the feeder tube, so that the diameter of the down-flowing glass is controlled by the spacing of the rod 8 from its surrounding feeder tube 6. By controlling temperature changes along the feeder tube 6 as well as the diameter and shape of the inserted rod 8, different size rods 10 can be obtained from the loose end of the control rod.

The container 2 can be made of platinum as well as the feeder tube 6, and the rod 8 could be an alloy of rhodium and platinum.
