Borosilicate Glass Coffee Cup – Heat-Resistant & Lead-Free | Home Office Cold Drink & Coffee Mug

Our borosilicate glass coffee cup is made of food-grade borosilicate glass, certified by SGS Food Safety Testing. It’s lead-free, cadmium-free, and odorless—safe for babies and pregnant women. We also offer two size options:

Have you ever had a regular glass cup crack instantly when pouring hot water? Do you worry about harmful substances from cheap glass? Or do you find cloudy cups ruin your drink’s appearance? Or struggle with cups that are either too small or too bulky?

First, it’s heat and temperature resistant, withstanding -20℃ to 150℃ without cracking. You can pour boiling water directly, hold cold drinks, or even refrigerate it (pair with our [silicone heat-resistant lid](link to lid product) for extra safety).

Second, it’s lead-free and non-toxic. Its strong chemical stability ensures no residual odor, preserving your drink’s pure taste.

Moreover, the transparent design showcases your drink’s color clearly. For example, the layers of an iced latte or the vibrant colors of fruit tea are perfectly displayed.

Finally, it’s 40% more shock-resistant than regular glass. It’s not easy to break from daily bumps, with a 3x longer service life.

Home Use: Breakfast hot milk, afternoon iced coffee, dinner fruit tea—two sizes fit the whole family. It’s also dishwasher-safe for easy cleaning.

Office Use: The 360ML large cup paired with our [stainless steel coffee spoon](link to spoon product) handles morning hot Americanos and afternoon iced sodas perfectly.

Summer Outdoor: The 340ML small cup is lightweight and portable, filled with iced coffee or cold brewed tea for a refreshing summer.

Gift Scene: The transparent and simple design, paired with a gift box, is ideal for friends or colleagues who value quality life.
