Abstract
A method of hermetically sealing a glass assembly comprising glass plates or substrates with a glass-based frit when there is a large difference between the coefficient of thermal expansion (CTEs) of the frit and the CTEs of the glass plates. The method comprises a rapid increase of an irradiating heat source, used to heat and soften the frit, from a non-sealing power to a sealing power over a very short distance along the frit to form an initial stabilizing seal between the substrates.
