How long does fire polishing take?

It depends on component size and complexity, but most jobs take 5–30 minutes. High-volume orders may use automated systems for faster processing.

Does fire polishing affect quartz glass’s strength?

No—if done correctly, it improves strength by removing surface defects (which are stress points) and relieving internal stress.

Can thin quartz glass components be fire polished?

Yes, but thin parts require extra care to avoid warping. An experienced provider will adjust flame intensity and movement speed to protect fragile components.

Is fire polishing the same as flame polishing for quartz glass?

Yes—they’re interchangeable terms. Both refer to the thermal process of melting and smoothing quartz glass surfaces with a high-temperature flame.

How does quartz glass compare to borosilicate glass?

Quartz glass offers superior performance : higher temperature resistance (1680°C vs 500°C), better thermal shock resistance, excellent UV transmission, lower thermal expansion (0.5 vs 3.3 ×10⁻⁶/K), and higher purity (99.99% SiO2). While more expensive, quartz glass is essential for high-temperature and high-purity applications where borosilicate glass cannot perform. Quartz glass also provides better optical transmission in the UV range (down to 185nm vs 300nm for borosilicate), higher chemical resistance to acids and alkalis, and superior dimensional stability at elevated temperatures. The higher cost of quartz glass is justified in applications requiring these superior properties, such as semiconductor processing, high-temperature furnaces, UV systems, and ultra-pure chemical processing. For lower temperature applications (<500°C) where UV transmission is not critical, borosilicate glass may be a cost-effective alternative.

What is the lead time for quartz glass orders?

Standard products typically ship within 7-14 business days . Custom fabricated components require 3-6 weeks depending on complexity and specifications. We maintain inventory of common sizes for faster delivery and offer expedited production for urgent requirements. For large volume orders, lead times may be extended but we work closely with customers to meet project deadlines. Rush orders can often be accommodated with additional fees. We provide regular production updates and tracking information once orders ship. International shipping times vary by destination but typically range from 5-15 days via air freight or 20-40 days via ocean freight. We work with reliable logistics partners to ensure safe, timely delivery worldwide.

Can you provide custom quartz glass components?

Yes, FGQuartz specializes in custom quartz glass fabrication . We offer precision machining, custom dimensions, specialized coatings, and unique geometries. Our engineering team works closely with clients to develop components that meet exact specifications for specialized applications. We can produce custom tubes with specific diameter/wall thickness combinations, rods with unique cross-sections, plates with precision-ground surfaces, and complex assemblies. Our capabilities include CNC machining, flame working, grinding, polishing, drilling, cutting, and joining. We provide prototyping services to validate designs before full production. Minimum order quantities vary by complexity, and we welcome both small-batch custom orders and large-scale production runs. Lead time for custom components is typically 3-6 weeks depending on complexity.

What industries use quartz glass products?

Quartz glass is essential in semiconductor manufacturing (diffusion tubes, wafer carriers), optical fiber production (preform manufacturing), laboratory equipment (crucibles, beakers), solar energy (photovoltaic processing), lighting (UV lamps), and chemical processing (high-purity reactors). FGQuartz serves all these industries with customized solutions. Additional applications include pharmaceutical manufacturing, aerospace testing, materials research, environmental monitoring, food processing (UV sterilization), water treatment, and specialty glass manufacturing. Our products are used by leading companies in electronics, telecommunications, energy, chemicals, and scientific research sectors worldwide.
