Abstract
The invention relates to a method for producing a glass article. The method includes the step of producing a glass body from a glass material and the further step of bringing the glass body, at a primary temperature which is at most 50 Kelvin below and at most 30 Kelvin above the Littleton softening point of the glass material, into contact with a liquid cooling agent which has a cooling agent temperature which is at least 200 Kelvin and at most 550 Kelvin below the primary temperature.
Claims27
A method for producing a glass article, characterized by steps as follows:
- a. producing a glass body (1) from a glass material, and
- b. contacting the glass body (1), at a primary temperature which lies at most 50 kelvins below and at most 30 kelvins above the Littleton softening point of the glass material, with a liquid cooling agent (4) which exhibits a cooling agent temperature which lies at least 200 kelvins and at most 550 kelvins, more particularly at least 200 kelvins and at most 450 kelvins, below the primary temperature.
