How to identify it at a glance and avoid it cleverly?

Glass has long been an indispensable material in our everyday lives, being utilized in construction, home furnishing and transportation - yet its quality on the market varies considerably; poor-grade products not only detract from aesthetic appeal but can even threaten safety.

1. Characteristics of inferior glass products

Uneven Color: Poor quality glass tends to feature irregular colors with black or white impurities visible, hindering its aesthetic appearance. Light Weight: Low-grade raw materials or inferior production processes could result in inferior glass having low density and light weight characteristics, leading to its light density and lightweight nature.
Sound Quality: When knocked, inferior glass will produce a dull and low sound; higher quality pieces produce crisp sounds when knocked. Rough Appearance: Low quality pieces often feature rough or uneven surfaces with burrs, impurities, bubbles or other defects on their surfaces compared to high quality pieces that may boast smooth surfaces without these types of defects.
Poor Transparency: Substandard glass has poor transparency and appears cloudy.

2. How to recognize substandard glass products

Examine for Bubbles and Impurities: Bubbles and impurities are hallmarks of inferior glass, so glass products should be closely examined for this condition.
Check Thickness and Edges: High-quality glass should have uniform thickness throughout, with straight and smooth edges without gaps between pieces. If there are uneven spots or rough edges present, that could indicate it could be of inferior quality.
Keep a sharp eye out for any glass products lacking a glossy surface or appearing dull; these could be signs of inferior glass quality.
Examine using Polarized Glasses or Sunlight: By using polarized glasses or sunlight, it's easy to spot whether tempered glass has colored spots or blue streaks; real tempered glass should show these characteristics.

3. Ways to spot inferior glass products

Consider selecting well-known brands and retailers: Brands with good name recognition are more likely to pay closer attention to product quality and after sales service, which will reduce the risk of purchasing inferior glass products.
Check product certification and logo: Since 2003, the glass industry has become more standardized; most tempered or laminated glass manufacturers now possess product certification certificates to reassure buyers. When purchasing, make sure the item displays either a 3C certification logo or certificate of conformity for quality assurance purposes.
Quality Check Products: Before making your purchase, carefully examine the color, weight, sound, appearance and gloss of glass products to ensure they meet high-quality glass standards.
Follow Product Instructions: It is important to carefully read through product instructions when using glass products to understand how and when they should be used so as to prevent breakages or damages due to misuse.
Avoid purchasing too inexpensive products: While price should not be the sole criterion in purchasing decisions, too cheap items could pose quality issues. When making this choice, be mindful of both price and quality issues when making this purchase decision.
