Beware of “Poison” from the Mouth: An Analysis of Risks from Substandard Cups (Part IV)

There are stories in every cup, warmth in every life—hello everyone, "Dong Dong's Cup Talk" is here. As people's pursuit of material comfort, convenience, and health grows, cups have evolved from optional accessories to essential items in daily life and work. However, some consumers prioritize affordability over quality, believing that cheaper means "better value." https://www.zhanyict.com/en/ProductsDetail-VB-10529.htmlUnbeknownst to them, unscrupulous businesses exploit this mindset by marketing substandard cups that often come with a host of issues, ranging from poor quality and craftsmanship to material safety concerns.

Today, as someone with years of experience in the cup industry, I will break down the risks associated with using non-compliant cups. Given my limited expertise, I have consulted numerous sources to compile this information. https://www.zhanyict.com/en/ProductsDetail-VB-10529.htmlIf you spot any inaccuracies or unclear explanations, please feel free to point them out. Due to the extensive content, I will organize the information into separate articles based on different materials.

Cups are our daily companions for hydration, and their material safety directly impacts our health. The diverse array of cup products on the market can turn into "health bombs" that slowly release harmful substances if they fail to meet production standards, https://www.zhanyict.com/en/ProductsDetail-VB-10529.htmluse inferior materials, or exhibit flawed craftsmanship. I will systematically analyze the hidden dangers of various types of substandard cups.

IV. Glass Cups: The "Dual Risks" in Clarity and Fragility

Glass cups are often considered the safest option, but they also come with pitfalls.

Types of Non-Compliance:

1. Mislabeled Materials:

Passing off ordinary soda-lime glass as high borosilicate glass. https://www.zhanyict.com/en/ProductsDetail-VB-10529.htmlThe former has poor thermal stability and is prone to cracking.

2. Physical Hazards from Improper Use:

Even compliant products carry risks of breakage due to impact or sudden temperature changes, which can result in cuts.

Core Harmful Substances and Health Impacts:

1. Impurities in Ordinary Glass:

While glass itself is relatively stable, substandard glass may contain heavy metals such as arsenic or antimony, https://www.zhanyict.com/en/ProductsDetail-VB-10529.htmlwhich pose a risk of minimal leaching when acidic liquids are stored for extended periods.

2. Physical Hazards:

This is the primary risk associated with glass cups. Sharp fragments from breakage can cause severe cuts.

Production Standards and Process Requirements:

1. Standards:

Materials must comply with the requirements of GB 4806.5-2016.

2. Processes:

High borosilicate glass must undergo strict annealing processes to eliminate internal stress and improve thermal shock resistance.
