Why is borosilicate glass used for glass coffee mugs?

Borosilicate glass is a type of glass that contains boron trioxide as a significant component in its composition. It is known for its unique properties and is used in a variety of applications. Some of the key characteristics of borosilicate glass include: High Thermal Resistance: Borosilicate glass is highly resistant to thermal expansion and can withstand a wide range of temperatures without cracking or shattering. This property makes it ideal for laboratory glassware, cooking and bakeware, and glass products used in high-temperature environments. Chemical Inertness: Borosilicate glass is relatively inert and resistant to chemical corrosion. It does not react with most chemicals, which is why it is commonly used for laboratory glassware where chemical reactions need to be observed or controlled. Transparency: Borosilicate glass is transparent, allowing for clear visibility and observation of the contents in containers and vessels made from this glass. This transparency is important in laboratory equipment and glass products used in the food and beverage industry. Durability: It is more durable and less prone to breakage than regular soda-lime glass. Borosilicate glass is often used for products that need to be both strong and resistant to thermal stress. Low Coefficient of Expansion: Borosilicate glass has a lower coefficient of thermal expansion compared to other types of glass, which means it expands and contracts less when exposed to temperature variations. This property contributes to its ability to withstand rapid temperature changes. One of the most well-known brands of borosilicate glass is Pyrex, which is used in kitchenware and laboratory glassware. It's commonly used in products such as beakers, test tubes, glass cookware, and high-quality glass pipes for smoking. Borosilicate glass is highly regarded for its ability to maintain its structural integrity under extreme conditions, which is why it is preferred for applications where safety, precision, and durability are essential.

The ideal cup size for a cappuccino typically ranges from 5 to 6 ounces or 150 to 180 millilitres. Take a look at the Rivers reusable cup range.

Cappuccinos are traditionally made with equal parts of espresso, steamed milk, and milk foam, resulting in a balanced and well-proportioned coffee beverage. Here's a general breakdown of the components in a cappuccino:

Espresso: 1 shot (approximately 1 ounce or 30 milliliters)
Steamed Milk: 1 ounce (30 milliliters)
Milk Foam: 1 ounce (30 milliliters)

These measurements may vary based on personal preferences and regional differences. Some people prefer a slightly larger cappuccino with a bit more milk or foam, while others prefer a more traditional and smaller 5-ounce cup.

Ultimately, the size of the cup you choose for your cappuccino depends on your personal taste and the balance you prefer between the espresso, milk, and foam. Using a cup in the 5 to 6-ounce range should give you a classic cappuccino experience, but feel free to adjust the ratios and cup size to suit your preferences.

A typical cup size for a flat white is smaller than a cappuccino or latte, and it's often served in a 5-ounce (150-millilitre) cup. The flat white is a coffee beverage that originated in Australia and New Zealand and is known for its balance of espresso and steamed milk, with a thin layer of microfoam on top. The smaller cup size helps maintain the strong coffee flavor while still providing a creamy and velvety texture from the milk and microfoam.

That said, the specific cup size can vary by region and personal preference. Some cafes and individuals might serve flat whites in slightly larger or smaller cups, but the 5-ounce cup is a common choice. The key to a good flat white is the balance between the espresso and the velvety milk, with the milk microfoam providing a smooth and consistent texture.
