Abstract

The invention relates to a method of reducing lead release from lead crys glass by applying a coating manufactured by application and hardening of a coating material containing a hydrolytic condensation product comprising a cross-linkable organofunctional hydrosilicon, a metal compound and an organic prepolymer cross-linkable with this hydrolytic condensate.
