Pyrex glass and borosilicate glass
Pyrex glass and borosilicate glass are two popular materials used in the production of glassware. While they may seem similar, there are key differences that set them apart.
What is Pyrex glass?
Pyrex glass is a type of glass that is made by adding boron to the traditional glass ingredients. This addition of boron increases the thermal shock resistance of the glass, making it more durable and less likely to break when exposed to extreme temperature changes.
What is borosilicate glass?
Borosilicate glass is a type of glass that is composed of silica and boron trioxide. This type of glass is known for its high resistance to thermal shock, making it ideal for laboratory glassware and cookware.
Key differences between Pyrex glass and borosilicate glass
One of the main differences between Pyrex glass and borosilicate glass is the thermal shock resistance. Borosilicate glass has a higher resistance to thermal shock compared to Pyrex glass, making it more suitable for applications where extreme temperature changes are common.
Additionally, borosilicate glass has a lower coefficient of thermal expansion compared to Pyrex glass, which means it is less likely to expand or contract when exposed to heat, reducing the risk of breakage.
Applications of Pyrex glass and borosilicate glass
Pyrex glass is commonly used in household glassware such as baking dishes, measuring cups, and storage containers. On the other hand, borosilicate glass is often used in laboratory glassware, industrial applications, and high-end cookware.
Overall, both Pyrex glass and borosilicate glass have their own unique properties and applications. Understanding the differences between these two types of glass can help you choose the right glassware for your specific needs.
