Newish Glass: The Art and Craft of Double-Walled Glass Coffee Cups

Описание: In the world of specialty coffee, the vessel is as crucial as the brew itself. At Newish Glass, we transform this truth into reality with our handcrafted double-walled glass coffee cups—where precision engineering meets artisanal craftsmanship to elevate every sip. Newish Glass company is a top ten glass factory in China, and worked with more than 80+ country clients in the world. Our double-walled cups are not just drinkware; they are a testament to our decades of expertise in glass manufacturing, designed to preserve flavor, enhance aesthetics, and stand the test of time for both home baristas and global café brands.
The journey of a Newish Glass double-walled cup begins with the selection of premium high borosilicate glass, a material renowned for its exceptional thermal resistance, clarity, and durability. Unlike ordinary soda-lime glass, high borosilicate can withstand rapid temperature changes—from freezing cold espresso shots to boiling pour-overs—without cracking or clouding. This makes it the ideal choice for double-walled construction, where two layers of glass work in harmony to insulate the drink and protect the hand. Our artisans source only the highest-grade borosilicate rods, ensuring every cup starts with a foundation of purity and strength.
Crafting a double-walled cup is a labor-intensive process that demands masterful skill. Each cup begins with two separate glass bubbles: an inner layer and an outer layer. Our glassblowers, with an average of 15+ years of experience, use traditional mouth-blowing techniques to shape the inner bubble into the precise form of a coffee cup—whether it’s a sleek espresso cup, a generous latte mug, or a compact espresso shot glass. The outer layer is then blown to fit snugly around the inner layer, creating a thin air gap between them. This gap is the secret to the cup’s insulation properties, keeping hot drinks warm and cold drinks chilled while ensuring the exterior remains comfortable to hold.
Quality control is woven into every stage of production. After annealing, each cup undergoes a rigorous inspection: our team checks for bubbles, imperfections, and structural integrity, rejecting any piece that does not meet our exacting standards. We test each cup for thermal shock resistance, dropping it from a controlled height to ensure it can withstand the rigors of daily use. Only cups that pass all tests move on to the finishing stage, where they are hand-polished to a brilliant, crystal-clear finish that showcases the beauty of the glass.
What sets Newish Glass apart is our commitment to customization, a capability that has made us a trusted partner for clients in 80+ countries.
