摘要： A redrawing method for the production of thin glasses is provided that allows redraw of high refractive index optical glasses. The includes the steps of providing a vitreous preform with a mean width B, a mean thickness D, and a refractive index nD of at least 1.68 in a redrawing device, heating at least a part of the preform, redrawing of the preform to a thin glass with a mean width b and a mean thickness d. The heated part of the preform exhibits, for the duration of at most 30 minutes, a temperature above a lower limit of devitrification of the glass. The glass of the preform exhibits a dependence of the viscosity on the temperature, which is characterized by a mean decrease of the viscosity with increasing temperature in an viscosity range of 108 to 105 dPas of at least 3*105 dPas/K.

摘要： A container for pharmaceutical and medical applications made from glass, preferably from a borosilicate glass. The container is formed in the shape of a hollow body open at both its ends with a cylindrical portion having a wall thickness tolerance of maximally ±0.2 mm. The borosilicate glass has a nominal boron content that drops by less than 40% relative to the nominal value at all of the surfaces of the container.
