At our factory, we place utmost importance on adhering to relevant quality standards to ensure the production of exceptional glassware. In this article, we aim to provide you with valuable knowledge on how to choose the right glass and introduce our company's top-quality products.
1. Whiteness: Opt for clear glass that exhibits no noticeable color or luster.
2. Air bubbles: Acceptable glass should have a limited number of air bubbles, while those that can be pierced with a steel needle are not allowed.
3. Transparent lumps: Ensure the glass body is evenly melted, with no more than one transparent lump measuring up to 1.0mm for cups below 142mL capacity. Cups ranging from 142mL to 284mL should have no transparent lumps covering more than 1/3 of the cup body.
4. Miscellaneous particles: Limit opaque granular impurities to a length of no more than 0.5mm, with a maximum of one particle.
5. Cup mouth roundness: The cup mouth should have a round shape, with a minimal difference of 0.7-1.0mm between the maximum and minimum diameter.
7. Low deviation of cup height: The height difference between the highest and lowest parts of the cup body should not exceed 1.0-1.5mm.
8. Thickness difference of cup mouth: Ensure the difference in thickness of the cup mouth does not exceed 0.5-0.8mm.
9. Shearing marks: Avoid marks exceeding 20-25mm in length and 2.0mm in width. Marks extending beyond the cup's bottom or appearing white and shiny are not allowed, and any marks exceeding 3mm should be avoided.
10. Die-printing: No obvious hidden imprints or record patterns should be visible when viewing the cup body from the top.
11. Cup body deflation: The cup body should not exhibit obvious unevenness when viewed from the top.
12. Wiping and scratching: Minimize traces of tarnishing caused by friction between the glass cup and its diameter, as well as bruises resulting from collisions between glasses. Shiny scratches are not acceptable.
