Abstract
A glass having a good hydrolytic resistance and alkali resistance is defined by a targeted combination of stoichiometric glasses, including glasses also existing as crystals in the same stoichiometry and whose properties can be assumed as being very similar due to the identical topology of the structural units for glass and crystal, respectively. A process of producing the glasses is also provided.
