Materials Used
What is Borosilicate Glass Material?
Borosilicate glass is a special type of glass made with silica and boron trioxide as its main components. It is known for its high resistance to thermal shock, durability, and clarity, making it ideal for products that are exposed to rapid temperature changes, such as laboratory equipment, kitchenware, and high-quality drinkware.



Double Walled Glass Mugs Production Process
The production of double walled glass mugs requires a highly skilled, handcrafted process using borosilicate glass. In the steps shown above, expert glassworkers shape and seal each layer using a high-temperature flame.
Each mug is formed by blowing and fusing two layers of glass—an inner chamber and an outer wall—together. This creates the signature insulated design that keeps beverages hot or cold while remaining comfortable to hold.
Once shaped, the mugs are heated and sealed by hand to ensure a perfect vacuum layer between the walls. This process demands precision, craftsmanship, and heat-resistant materials, making each mug both functional and beautiful.
DM Glassware takes pride in offering high-quality, handcrafted double walled glass mugs made with care, clarity, and lasting durability.
