The invention provides a kind of can being applied in and on medical ampoule, play the skill that makes the easy to break and decoration functions of ampouleArt, is coated with one deck color glaze as thin as a wafer on bent neck ampoule neck surface, swollen owing to existing between color glaze and ampoule bottleThe difference of swollen coefficient, just can form concentrated stress at the recess of ampoule neck, makes ampoule be easy to fracture.This characteristic makes glass ampule both easy to use, safety and sanitation again; Also can be used for preparing colored glazed glass.
If add base glaze quality by a large amount of only experimental studies have found that with molten addition in base glaze system0～5％SnO2、0～10％TiO2Time, opaque effect is not obvious; And by mill addition method at above-mentioned base glaze glass dustIn 2%～12%TiO of additional base glaze quality2Time, opaque effect is good. So the present invention adopts two additions,The first molten base glaze quality 5%TiO that adds2(or SnO2) in base glaze, for improving refractive index and the glossiness of color glaze,Regrind and add the 10%TiO of base glaze quality2Opaque effect the best, final temperature of glaze firing scope is at 580～660 DEG CBetween, meet the requirements. , can reach more than 75% color glaze measuring brightness by whiteness instrument.
