During this period, the varieties of glassware are rich and varied, and the shape and decoration are also changed. The material is made into the bottle, bowl, snuff bottle, bird and beast, etc. with vivid color and unique style and charm.
The glassware is a colorless transparent ware made of soda-lime-silicate glass, and the iron content in the glass is generally lower than 0.02%. Adding a colorant into the glass raw material to prepare colored glass; adding an opacifier to prepare the opacified glass. The high-grade artistic utensils such as goblets, perfume bottles and fruit bowls are made of potassium lead silicate glass, also called lead crystal glass. The glass contains PbO, has high refractive index and dispersion, is extraordinarily bright when being milled with an engraved edge surface, has high specific gravity, and generates crisp sound when being knocked. The lead-free glass contains more than 30% of PbO, 24-30% of PbO, less than 18% of PbO and BaO. The products of the cooking utensils such as coffee pot and the like are made of heat-resistant borosilicate glass, and the heat expansion coefficient is low and the temperature shock resistance is strong. The microcrystal glass has better heat resistance and temperature shock resistance, has high mechanical strength, and is suitable for manufacturing cooking utensils and utensils which are frequently washed in restaurants and hotels.
Glassware based on glass has a wide range of applications, and a series of research on the component formula and process improvement of glassware is reported successively. For example, Chinese patent numbers are: CN20131025011.3 discloses a "fluoride-free environment-friendly glass cup", through this technical scheme, effectively lower the fluoride content in the glass cup, play an environmental protection role to a certain extent, however, because fluorine element exists in a relatively stable combination form in the glass cup, and the content is not high, therefore, the harm to human body and environment is less. However, the technical scheme has the defects that the obtained glass cup has weak mechanical hardness and falling resistance and has a narrow application range. Aiming at the defects in the prior art, an effective implementation mode is not provided so far.
