2018-04-02

　　1、白度：對明料玻璃要求無顯著色澤。
　　
　　2、氣泡：允許一定寬度、一定長度的氣泡存在一定的數量，而能用鋼針刺破的氣泡不允許存在。
　　
　　3、透明疙瘩：指熔融不均勻的玻璃體，對容量小于142L的玻璃杯，長度不大于1.0mm的不多于一個；對容量為142~284mL的玻璃杯，長度不大于1.5mm的不多于一個，杯身1/3的透明度疙瘩不允許存在。
　　
　　4、雜粒：指不透明的粒狀雜物，長度不大于0.5mm，不多于1個。
　　
　　5、杯口圓度：指杯口不圓，其最大直徑與最小直徑差不大于0.7~1.0mm.6、條紋：距離300mm目測明顯的不允許有。
　　
　　6、杯身高低偏差（杯身高低偏斜）：一只杯子杯身最高處與最低處的高度差不大于1.0~1.5mm。
　　
　　7、杯口厚薄差：不大于0.5~0.8mm.
　　
　　8、剪切?。褐笚l紋或蜈蚣狀剪切痕，長度不大于20~25mm，寬度不大于2.0mm的不多于1條，超過杯底，或發白發亮，超過3mm的不允許有。
　　
　　9、模?。罕沓食y路的隱印，平視明顯的不允許有。
　　
　　10、杯身吸癟：指杯身凹凸不平，平視明顯的不允許有。
　　
　　11、擦毛與擦傷：擦毛指玻璃杯與玻璃杯直徑的摩擦，在杯身留下失去光澤的痕跡，平看明顯的不允許有。擦傷指玻璃杯之間相互碰撞，在杯身表面留下的傷痕，發亮的不允許有。
1 whiteness: there is no obvious color for glass requirement.
2 bubble: allow certain width certain length bubble exists certain quantity but can be broken by steel needle can not allow existence.
3, transparent keloid: vitreous body with uneven melting volume; less than 1 glass length less than 1.0 mm in length less than 142 mm; no more than 1.5 mm length for glasses with volume 142 ~ 284 m; Transparency knots of cup body 1/3 are not allowed.
4, miscellaneous granules: opaque granules, length not greater than 0.5 mm, not more than 1.
5 cup roundness: refers to cup not round, its maximum diameter and minimum diameter difference is not greater than 0.7 ~ 0 mm, stripes: distance 300 mm visual obvious not allowed.
7 cup height deviation (cup height low deflection): one cup body height and lowest height difference is not greater than 1.0 ~ 1.5 mm.
8, thickness difference of cup: not greater than 0.5 ~ 0.8 mm.
9, shear printing: finger stripes or centipede shear scars, length less than 20 ~ 25 mm, width less than 2.0 mm, not more than 1, exceeding cup bottom, or hair, more than 3mm cannot be allowed.
10, mould printing: Cup body shows record grain hidden print, head-up obviously does not allow.
11 cup body suction flat: refers to cup body uneven, head-up obvious not allowed.
12, wiping and abrasions: rubbing refers to friction between glass and glass diameter, leaving traces of shiny luster in cup body, flat view obviously not allowed. Bruises refer to collisions between glasses, scars left on glass surfaces, shiny ones not allowed.
