Method and apparatus for forming a glass tube from a glass preform |
| abstract |
A method for forming a glass tube is disclosed. In one embodiment, the method comprises heating the glass fired to a temperature above the glass transition temperature of the glass fired, drawing the glass tube out of the glass fired in a vertically downward direction, And flowing the gas. The glass frit includes an outer surface defining an outer diameter of the glass frit and a channel extending through the glass frit forming an inner diameter of the glass frit. The step of drawing the glass tube reduces the outer diameter of the glass bulb to the outer diameter of the glass tube and the step of flowing the pressurized gas through the channel increases the inner diameter of the glass bulb to the inner diameter of the glass tube. Glass fires, glass tubes, and devices for making them are also described. |
