Abstract
The disclosure is of a method of preparing an envelope assembly including a glass tubulation in which the tubulation includes a portion of reduced diameter at which a tip-off is formed during the manufacturing process. The method comprises heating the tubulation to an elevated temperature at which surface defects heal, and subsequently securing the tubulation to the envelope in normal fashion while insuring that no further surface defects occur.
