Technical Description Based on the Materials Used in Its Manufacturing:

  1. Capacity:

    Volume: 296 ml (milliliters). This is the maximum amount of liquid the glass can hold. The 296 ml size is ideal for serving individual portions of beverages such as water, juices, sodas, or cocktails.

  2. Materials Used:

    The blown glass is made from a special glass formula consisting of several components, which provide it with durability, temperature resistance, and good transparency:

Sodium and Calcium Carbonate (Na₂CO₃ and CaO): These two compounds are essential in the formulation of glass. Sodium carbonate is used as a flux that lowers the melting temperature of silica sand, facilitating the production of glass. Calcium is used to improve the chemical stability of the glass, making it more resistant to moisture and acid attack, thus enhancing its durability.

Aluminum Hydroxide (Al(OH)₃): Aluminum hydroxide acts as a reinforcer in the glass. Its presence helps to increase the thermal resistance and stability of the glass, as well as reduce thermal expansion. This makes the glass more resistant to sudden temperature changes, which is useful when used for both hot and cold beverages.

Silica Sand (SiO₂): Silica sand is the primary ingredient in glass production. Silicon dioxide (SiO₂) provides the basic structure of the glass, adding transparency and strength to the glass. This material is insoluble in water and provides the most distinctive feature of glass: its ability to be translucent and resistant to abrasion.

Ground Glass: Ground glass is used to recycle the material and reinforce the structure of the glass, improving its mechanical strength. Ground glass also contributes to the consistency of the manufacturing process and can enhance aesthetic properties by adding a particular texture to the glass.

Manufacturing Process: Glass Blowing

The glass is made using the blowing process. This process involves heating the material mixture until it melts (at temperatures close to 1,200°C) and then blowing it into a mold to shape it. Blowing allows the glass to take a uniform, smooth, and seamless shape, which is essential to create a functional and aesthetically pleasing glass.

  1. Material Properties:

Thermal Resistance: Thanks to the inclusion of aluminum hydroxide in its composition, this glass has an enhanced ability to resist sudden temperature changes, making it suitable for both hot and cold beverages. The material can withstand thermal variations without suffering significant structural damage, which is common in other types of unreinforced glass.

Transparency and Shine: The use of silica sand and the specific composition of the glass give the glass high transparency and a shiny finish, allowing for clear visibility of the contents. Transparency is an important feature, especially in glasses used for beverages, as it enhances the visual perception of the color and quality of the liquid inside.

Mechanical Strength: The presence of ground glass and sodium carbonate in the mixture improves the impact resistance and structural solidity of the glass, making it more durable and less likely to break with light drops or knocks.

Chemical Stability: The compounds of calcium and sodium carbonate enhance the chemical stability of the glass, reducing its susceptibility to attack from acidic or alkaline substances. This ensures the glass does not deteriorate easily over time, even with frequent contact with acidic or alkaline liquids.

  1. Dimensions and Design:

Height: The glass has a standard height of approximately 10-12 cm, depending on the specific design.

Diameter: The top diameter may vary between 8-10 cm, providing a balance between functionality and comfort when drinking.

Shape: The glass has a cylindrical or slightly curved shape in some designs, with rounded edges that promote grip and practical use.

Applications and Uses:

This type of blown glass is ideal for a wide range of applications:

Household Use: Perfect for serving beverages at home, from water, juices, to alcoholic drinks or cocktails.

Hospitality and Restaurants: Its transparency and strength make it suitable for use in restaurants, bars, and other beverage-serving establishments.

Events and Catering: Due to its elegant design and the option for mass production, it is ideal for events, banquets, or celebrations.

Additional Properties:

Scratch Resistance: Thanks to the glass composition, this glass is less susceptible to scratches compared to other softer materials.

Food Safety: The glass used in the manufacturing process meets food safety standards, ensuring it does not release harmful substances when in contact with food and beverages.
