Our production process
BO-GLASS specializes in customized glass molding services, offering end-to-end solutions from prototype development to mass production. Our China-based facility features a 10-ton daily capacity borosilicate glass furnace, in-house tempering ovens with high-pressure air quenching systems for rapid cooling, and comprehensive post-processing equipment including precision cutting, polishing, and grinding. We deliver high-quality glass components of any size or complexity, supported by expert technical guidance, optimized production workflows, and seamless design-to-manufacture transitions, ensuring efficient project execution with competitive pricing and tailored engineering solutions.
Heating & Shaping
The glass is melted using a gas-oxygen torch, allowing precise temperature control. Molten glass is wound onto a mandrel or shaped directly with tools (tweezers, paddles) to create beads, vessels, or intricate designs. For hollow forms (e.g., tubes), air is gently blown through a blowpipe into the molten glass to expand it.
Detail Work
Colors or patterns are added by layering or fusing additional glass strands. Complex designs (e.g., twists, dots) are crafted through controlled reheating and manipulation.
Controlled cooling
Once the glass is formed, it must be cooled gradually to prevent cracks or breakage due to internal stresses. If the Annealing: Finished pieces are placed in a kiln to cool slowly, relieving internal stresses and preventing cracking.
Finishing
Surfaces are polished, and any sharp edges are smoothed via grinding or flame polishing.
Quality inspection packaging
Our team of highly-trained packaging specialists will expertly craft premium-quality packaging solutions that showcase your products in their most elegant light.

Materials
High Borosilicate Glass Tubing (COE 33):
Composition: Primarily silica (≈80%) and boron trioxide (≈13%), with minimal alkali content.
Key Properties: Exceptionally low coefficient of thermal expansion (CTE ~33 x 10⁻⁷/K). This grants outstanding thermal shock resistance.
Processing: Specifically designed for direct flame working (“lampworking”). Its low CTE allows rapid, localized heating and cooling without cracking, enabling complex shaping.
Performance: Highly resistant to thermal stress, chemicals, and thermal cycling. Maintains clarity and structural integrity under temperature changes.
Result: Ideal for precisely forming intricate, durable glass lampshades via flame manipulation, as it can withstand significant thermal gradients during shaping. Its surface is inherently smooth.
Material Advantages:
Exceptional Thermal Shock Resistance: The low coefficient of thermal expansion (COE ~33) enables rapid, localized heating and cooling with the torch without cracking, crucial for detailed manipulation and assembly.
High Working Temperature Stability: Maintains viscosity and shape integrity at flame-working temperatures, allowing precise control over forming.
Superior Mechanical Strength & Durability: Results in thinner, lighter, yet highly robust lampshades resistant to breakage and thermal stress during use.
Chemical & Thermal Resilience: Highly resistant to water, chemicals, and thermal cycling, ensuring long-term clarity and performance in lighting applications.
Inherently Smooth Surface: Delivers excellent optical clarity without requiring extensive surface finishing post-working.
