An In-Depth Analysis of Glass Cup Manufacturing — Core Materials Part II

Every cup tells a story, and life is filled with warmth. Hello everyone, "Dong Dong's Cup Talk" is here. Recently, due to the economic environment, I’ve had to spend more time seeking orders, which has slowed down the pace of content creation. https://www.umbottle.com/ProductsDetail-VB-10332.htmlAs a result, I’ve adjusted my updating approach—after sharing analytical content, I often follow up with product showcases due to the slower update cycle. This might leave some friends feeling unsatisfied.

I deeply apologize to everyone and hope you will continue to support me as always. I will quickly readjust and, in the future, share plenty of practical and in-depth analytical content with you all. At the same time, I also need your help in terms of business opportunities. https://www.umbottle.com/ProductsDetail-VB-10332.htmlHere, I bow to you in gratitude and wish everyone prosperity and abundant wealth.

Today, I bring you an in-depth analysis of glass cup manufacturing. Through this article, I hope to help you clearly understand what materials are used to make the glass cups you currently use and how to choose the right glass cup when making a purchase in the future. https://www.umbottle.com/ProductsDetail-VB-10332.htmlDue to the extensive content, I will divide it into multiple parts to share with you.

Many friends who use glass cups or glassware in their daily lives may not be familiar with the materials used in manufacturing glass cups. For example, what is soda-lime glass? What is glassware made from low borosilicate material? What is a glass cup made from medium borosilicate material? And what about high borosilicate glass cups? https://www.umbottle.com/ProductsDetail-VB-10332.htmlWhat are these materials exactly? Here, I won’t go into detail about soda-lime glass but will focus on the common materials used for everyday glass cups.

Medium Borosilicate Glass (Boron Oxide Content: 8-12%)

Characteristics: Balanced performance, moderate thermal expansion coefficient (approximately 4-5 x 10⁻⁶/K), https://www.umbottle.com/ProductsDetail-VB-10332.htmland good thermal shock resistance (withstands temperature differences up to 120°C).

Suitable Cup Types: Everyday water cups, coffee cups, tea cups, and heat-resistant glassware. It is a cost-effective choice.

Performance: Offers good strength, heat resistance, and chemical stability.

Case Study: Mainstream tea shops widely use medium borosilicate glass for takeaway cups, balancing cost and heat resistance requirements.

Safety: Internationally recognized as a safe material, https://www.umbottle.com/ProductsDetail-VB-10332.htmlwidely used in pharmaceutical packaging.

Simple Identification: Relatively high transparency, moderate wall thickness, and produces a clear, crisp sound when tapped.
