Engineering Overview & Manufacturing Capabilities
Hejian City manufactures over 70% of China's heat-resistant borosilicate glassware and exports to more than 60 countries. Our glassware factory blends generations of mouth-blown artisan glass techniques with modern annealing lehrs to create elegant, thermal-shock resistant teapots, double-wall cups, coffee drippers, and kitchen carafes.
Crafted from medical-grade 3.3 expansion coefficient borosilicate glass, our teapots withstand extreme instantaneous temperature differentials ranging from -20°C up to +150°C (-4°F to 302°F). You can safely pour boiling water directly into an ice-filled pot, or place it directly on an open flame gas stove or electric ceramic burner without risk of thermal stress fracture. The material is 100% lead-free, non-porous, and chemical-resistant, ensuring pure flavor without chemical leaching or staining.
The teapot features a precision laser-slotted glass or 304 stainless steel infuser that captures loose leaf tea leaves while allowing optimal water circulation. Spouts are handcrafted with anti-drip eagle-mouth profiles for clean, splash-free pouring. Each piece is annealed in computer-controlled electric tunnel kilns for 4 hours to relieve internal residual stresses, guaranteeing crystal clarity and commercial dishwasher durability.
Industrial Cluster Deep Dive & Supply Chain Edge
Hejian City (河间市), Cangzhou
The Heat-Resistant Borosilicate Glassware Capital of ChinaLocalized Ecosystem: Hejian possesses an unmatched industrial supply chain for high-borosilicate glass products. Within Hejian, high-purity borosilicate raw tube melting factories, automated bottle blowing facilities, artisan torch-blowing studios, natural bamboo lid woodturners, 304 stainless steel stamping plants, and custom drop-proof EVA foam packaging factories work in seamless proximity.
The "Neijuan" Source Factory Edge: Extreme specialization and localized raw material tube drawing give Hejian factories an unshakeable price advantage. While retail stores in Europe or North America sell borosilicate glass teapots for $20.00 - $35.00, Hejian direct 1688 source factory prices are only $1.85 - $3.80 per unit, allowing lifestyle brands and kitchenware importers to enjoy high profit margins.

End-to-End Production & Quality Control Process
Raw 3.3 Borosilicate Glass Tube Inspection
High-purity borosilicate glass tubes are inspected for wall thickness uniformity, bubble inclusions, and optical clarity using polariscopes.
Artisan Flame-Working & Torch Mouth-Blowing
Glass tubes are heated to 1,600°C over natural gas-oxygen torches. Master glassblowers shape the teapot body, attach ergonomic handles, and form non-drip spouts.
Precision Laser Slotted Infuser Fabrication
Glass infuser cylinders are cut with ultra-fine 0.5 mm laser drainage slits to filter fine tea leaves without clogging liquid flow.
4-Hour Controlled Tunnel Annealing
Teapots pass slowly through a 35-meter electric annealing lehr, cooling gradually from 560°C to room temperature to eliminate internal molecular stresses.
Thermal Shock Testing & Drop-Proof Packing
Random samples are tested directly from -20°C freezer to 100°C boiling water. Products are packed in form-fitted high-density pearl cotton / EVA boxes.
