The present invention is directed to the preparation of frit pastes suitable for sealing together preformed glass parts, being especially suitable for sealing glass panels to funnels of cathode ray tubes. The pastes comprise a mixture of frit particles, a lacquer, and at least one additive in an amount of 0.0005-2% by weight total of the lacquer. The preferred additives are selected from the group of alkyl organic phosphate esters, a mixed titanium ortho ester complexes, and substituted sorbitols in the polyol acetal family.
