When considering the glass utilised in crafting glassware, you might be taken aback to discover the availability of multiple glass materials. This distinction is generally what delineates between using glasswares of lesser and higher quality. Despite the outward similarity in appearance among different glass types, there exist substantial disparities in terms of construction and the glass's inherent composition. This is particularly true for two highly favoured glass types—borosilicate and crystal or regular glass.

Borosilicate glass and regular glass (often referred to as soda-lime glass) are two distinct types of glass with different compositions and properties. Here are the key differences between them:

Composition:

Borosilicate Glass: Borosilicate glass is composed primarily of silica (silicon dioxide) and boron oxide. The addition of boron oxide gives this glass its unique properties, including high thermal resistance and low coefficient of thermal expansion.

Regular Glass (Soda-Lime Glass): Soda-lime glass is composed of silica, soda (sodium oxide), and lime (calcium oxide), along with small amounts of other additives. This type of glass is more common in everyday applications like windows, bottles, and containers.

Thermal Resistance:

Borosilicate Glass: Borosilicate glass has a very low coefficient of thermal expansion, which means it can handle rapid temperature changes without cracking. It is highly resistant to thermal shock, making it suitable for applications involving high temperatures and temperature variations.

Regular Glass: Soda-lime glass has a higher coefficient of thermal expansion compared to borosilicate glass. This means it's more prone to thermal stress and can crack when exposed to rapid temperature changes.

Chemical Resistance:

Borosilicate Glass: Borosilicate glass is highly resistant to chemical corrosion and attack by acids and other chemicals. It is commonly used in laboratory equipment due to its ability to withstand contact with reactive substances.

Regular Glass: Soda-lime glass is less chemically resistant compared to borosilicate glass. It can be corroded or degraded by certain chemicals and acids.

Optical Clarity:

Borosilicate Glass: Borosilicate glass offers excellent optical clarity and is often used in applications where transparency and clear visibility are important.

Regular Glass: Soda-lime glass also provides good optical clarity and is commonly used for windows and glass panels.

Durability:

Borosilicate Glass: Due to its thermal and chemical resistance, borosilicate glass is generally more durable and long-lasting than soda-lime glass.

Regular Glass: While soda-lime glass is not as resistant to thermal and chemical stress as borosilicate glass, it is still widely used and durable in many applications.

Applications:

Borosilicate Glass: Borosilicate glass is commonly used in laboratory glassware (beakers, flasks, test tubes), cookware, lighting fixtures, optics, and various industrial applications.

Regular Glass: Soda-lime glass is used for windows, bottles, containers, glassware, and general-purpose applications.

Cost: Borosilicate glass tends to be more expensive to produce than regular glass due to its unique properties and composition. This cost difference can influence which type of glass is used in various products.

In summary, while borosilicate glass is widely used in specific applications that require its unique properties, regular glass (soda-lime glass) is more commonly found in everyday items. The choice between these two types of glass depends on the intended use, required properties, and budget constraints of the application.

At Boropuff we think that borosilicate glass is a significant upgrade from traditional glass, its excellent technical characteristics can make a big impact on both our personal health, our everyday experiences and the environment, when compounded over time.
