2, bubbles: a certain width and length of bubbles are allowed to exist in a certain number, while bubbles that can be pierced with a steel needle are not allowed to exist.
3, transparent lumps: refers to the melt uneven glass body, for the capacity of less than 142mL glass, the length of not more than 1.0mm not more than one; for the capacity of 142 ~ 284mL glass, the length of not more than 1.5mm not more than one, the glass 1/3 of the transparency lumps are not allowed to exist.
4, miscellaneous particles: refers to the opaque granular debris, length not more than 0.5mm, no more than one.
5、Cup roundness: refers to the cup is not round, its maximum diameter and the minimum diameter difference is not more than 0.7 ~ 1.0mm. 6、Stripes: distance 300mm visually obvious is not allowed.
7, cup height deviation (cup height skew): a cup cup height difference between the highest and lowest is not more than 1.0 ~ 1.5mm.
8, cup thickness difference: not more than 0.5 ~ 0.8mm.
9, shear marks: refers to the stripes or centipede-like shear marks, the length of not more than 20 ~ 25mm, the width of not more than 2.0mm not more than 1, more than the bottom of the cup, or shiny white, more than 3mm is not allowed.
10, mold marks: cup body is a record pattern of hidden marks, flat view of the obvious is not allowed.
11, the cup body suck deflated: refers to the cup body uneven, flat view of the obvious is not allowed.
12, rubbing hair and abrasion: rubbing hair refers to the friction between the glass and the diameter of the glass, leaving traces of loss of luster in the body of the glass, flat look obvious is not allowed. Abrasion refers to the mutual collision between the glass, leaving a scar on the surface of the cup, shiny is not allowed.

Maintenance

Although the glass is transparent and good-looking, but not easy to preserve, must be carefully placed. In fact, in all materials of the cup, the glass cup is the healthiest. Because glass cups do not contain machine chemicals, when people drink water or other drinks with glass cups, do not have to worry about harmful chemicals will be drunk into the stomach, and the glass surface is smooth and easy to clean, so people drink water with glass cups is the healthiest and safest.
Double-layer glass
Glass cups every time after use such as can immediately clean the best, if you think it is too much trouble, should also be at least once a day to clean, can be washed at night before going to bed, and then dried. When cleaning the cup, not only to clean the mouth of the cup, the bottom and the wall should not be ignored, especially the bottom of the cup, usually not often cleaned, may precipitate a lot of bacteria and dirt. Professor Cai Chun especially reminded women friends, lipstick not only contains chemical ingredients, and very easy to adsorb harmful substances in the air and pathogens, drinking water will bring harmful substances into the body, so the lipstick residue in the cup must be cleaned. Washing the cup with water is not enough, it is best to use a brush.

If you want to clean the cup with a lot of grease, dirt or tea scum, you can squeeze toothpaste on the brush and scrub back and forth inside the cup. Since toothpaste has both a stain remover and a very fine rubbing agent, it is easy to wipe away the residual material without damaging the cup.
