Double-wall glass cups are a trendy accessory for any beverage connoisseur. They are durable, and stylish and keep your hot drink hot and cold drinks cold for a longer period. However, some of these cups might come with a tiny closed hole/indention on the bottom of the cup. So why is it there? And will it affect your drinking experience?

Firstly, it is important to understand that this tiny closed hole/indention is a purposeful design on the cup. It is called a vacuum layer, which is created by fusing two layers of glass. The vacuum layer is created to ensure the temperature of the liquid inside the cup can be maintained for a longer period.

The vacuum layer works simply. When you pour hot or cold liquid into the cup, it heats or cools the inner glass layer. However, the outer glass layer is not in direct contact with the liquid, which means that it is not affected by the temperature change. As such, it acts as an insulator, preventing heat or cold from escaping the cup. This insulation layer is the vacuum layer, and it is what keeps your beverage at its desired temperature for a longer period.

The reason for the tiny hole/indention on the bottom of the cup is to release any air that is trapped between the two glass layers when the vacuum layer is formed. Creating a hole in the base, allows the air to escape and ensures that no bubbles remain trapped in between the layers. This is important as any trapped air between the layers can affect the vacuum insulation of the glass cup. This also ensures that the glass cup maintains its insulating properties.

In addition to maintaining the temperature of your beverage, double-wall glass cups also provide an aesthetic appeal. The construction of the vacuum layer gives the cup a unique look that is sure to turn heads. It also makes the cup more durable as it provides an added layer of protection.

Some people might be concerned that the hole/indention will affect their drinking experience or make it difficult to clean the cup. However, the hole is small enough that it does not cause any discomfort when drinking from the cup. It is also not hard to clean as it is located on the bottom of the cup and is easily reached with the tip of a cleaning brush.

In conclusion, the tiny closed hole/indention on the bottom of double-wall glass cups is a vital component of the cup's insulation system. It is important to ensure that this design element is present if you want your cup to maintain its insulation properties. With this vacuum layer, users can enjoy their hot or cold beverage for a longer period while also having a unique and stylish accessory to show off.
