Glass cups are an indispensable part of cultural life, renowned for their exquisite craftsmanship. So, what process does it take to make a glass cup? This article will take you on a closer look:

1. Pouring

1.1 Preparation of raw materials

Firstly, to manufacture glass cups, a series of materials mainly composed of glass and glass melt nodules need to be prepared. List materials, among which glass and molten nodules are essential raw materials. Other raw materials can vary according to operational requirements.

1.2  Molten glass

Next, the production of molten modules in glass cups requires different color requirements and melting. The requirement for the tumor is to melt it to ensure the quality and color of the final glass cup.

1.3 Injection mold

Finally, pour the melted glass into a specific mold to form the shape of a glass cup on its metal inner surface, and then place it in a firing kiln for firing.

2. Firing

2.1 Temperature control

The key to firing glass cups lies in temperature control. Therefore, it is necessary to put the glass cup into the firing kiln, control the temperature within a certain range according to different formulas, and manufacture the desired shape of the glass cup.

2.2 Exterior firing

Next, we will proceed with exterior firing, using the whirlwind inside the firing kiln to adjust the shape of the glass cup to ensure a delicate and stable exterior appearance.

2.3 Cooling

Finally, during the cooling process, the air in the glass cup is discharged to ensure the flatness and integrity of the final glass cup, and to ensure that the glass cup has sufficient hardness.

3. Polishing and Completion

3.1 Polishing

 Next, after the glass cup is fired and cooled, there may be some varying degrees of defects, which require polishing to ensure a smooth and perfect final surface of the glass cup.

3.2 Film application

 Finally, after polishing, it is necessary to apply a film to the glass cup to increase its aesthetics and service life, in order to complete the final design and production of the glass cup.

How is a glass cup made? The complete production process of glass cups requires not only patient and exquisite craftsmanship, but also precise control of materials and temperature in order to make the ultimate ideal glass cup.

First of all, it is worth noting that food grade glass cups are made of high quality silicone glass material and are environmentally friendly materials. The maximum temperature range of food grade glass cups can reach 150 degrees Celsius, and the lowest temperature that can withstand low temperatures can reach minus 20 degrees Celsius. This type of glass material can not only withstand large instantaneous temperature differences, but also immediately connect to high temperature hot water after being filled with ice water, and the glass will not explode. Not only that, it also has the advantages of wear resistance and acid and alkaline resistance, so it can completely hold various liquid substances such as fruit juice, tea drinks, and carbonated drinks.

If a consumer purchases a calcium silicate glass cup, they must remember not to use it to hold hot water. If a consumer purchases a tempered glass cup, before using it to hold hot water, they must remember to raise the temperature of the cup body with warm water, reduce the temperature difference, and then pour in hot water. Of course, in order to ensure the safe use of glass cups, it is recommended that consumers purchase high borosilicate glass cups. This way, whether it is filled with hot water or cold water, it is very safe.
