2022-04-20
The application of glass is very extensive and applicable to various occasions. Now there are more and more kinds of glass on the market, which has been favored by consumers. In fact, when we choose a glass, we need to pay attention not only to the price, but also to the different materials of glass, so as to select a suitable glass. Today, I will list several methods of selecting glass, hoping to help you.
1. Whiteness of glass: for some transparent glasses, there should be no obvious color
2. Bubbles in the glass: some bubbles on the glass body are allowed, but some large bubbles need to be strictly controlled
3. Transparent pimples: for glasses with a capacity of less than 140ml, pimples with a length of no more than 1mm are allowed. For glasses with a capacity of more than 140ml, there are no more than one pimple with a capacity of no more than 1.5mm in Changzhou, and 1 / 3 of the transparent pimple of the cup body is not allowed
4. Miscellaneous particles: no more than 0.5mm in length and no more than one
5. Roundness of cup mouth: the diameter difference of cup mouth should not be greater than 0.7 to 1mm
6. Stripes: visible stripes are allowed at a distance of 300mm
7. Height deviation of cup body: the height difference of each cup should not be greater than 1 ~ 1.5mm
8. Thin wall of cup mouth: the thin wall difference of each cup mouth shall not be greater than 0.5 ~ 0.8mm
9. Impression: no obvious impression is allowed on the cup body
