Quartz Glass Manufacturer: Custom Quartz Glassware, Tubes, Crucibles and Wafer Boats
FGQuartz is a quartz glass manufacturer in Lianyungang, China. We make standard and custom fused silica (SiO₂ ≥ 99.99%) tubes, rods, plates, wafer boats, crucibles, tanks and inline heaters, plus one-off parts from a drawing, a sample or a sketch. No minimum order, and quotes within 24 business hours.
Quartz Glass Products
Every product is available in standard sizes or made to your drawing. Choose a product to see sizes, grades and how to order.
Quartz Boats and Wafer Boats
Wafer boats and carriers for diffusion, oxidation and annealing furnaces, with slot pitch and count to your wafer size.
Quartz Crucibles
Cylindrical and custom fused quartz crucibles for melting, ashing and high-temperature processing.
Quartz Glass Tubes
Fused silica tubes, including large-diameter and closed-end, for furnaces, lamps and process lines.
Quartz Glass Plates
Clear and optical-grade fused silica plates, cut and polished to size.
Quartz Glass Rods
Fused silica rods in standard diameters, cut to length or machined to a drawing.
Quartz Tanks
Cleaning and etching tanks for wet-process lines. Resistant to hot mineral acids, not to HF.
Quartz Inline Heaters
Inline heaters for high-purity liquids and gases.
Custom Quartz Glass
One-off and repeat parts made from your drawing, sample or sketch.
Quartz Glass for Your Industry
Pick the process you run to find typical quartz parts and material notes for it.
Semiconductor
Wafer boats, tubes and furnace parts for diffusion, oxidation and CVD.
Optical
Windows, plates and optical-grade fused silica for UV and visible light.
Laboratory
Crucibles, beakers, cells and glassware for analysis and sample preparation.
High temperature
Furnace tubes, liners and supports for service up to 1200°C.
Solar photovoltaic
Boats, tubes and carriers for solar cell diffusion and processing.
Fiber optic
Tubes and rods for preform and fiber manufacturing.
Custom Quartz Glassware from a Drawing, Sample or Sketch
You do not need a finished drawing. Our engineers start from a CAD file (DXF, STEP, IGES, PDF), a hand sketch, photos, a worn sample, or a plain description of what the part must do.
Hot work (flame forming, bending, sealing, welding) and cold work (diamond cutting, drilling, grinding, polishing) happen in the same plant, followed by annealing and inspection. One team handles quartz parts manufacturing from first cut to final check.
Typical requests: matched sets of crucibles or beakers, multi-port vessels, closed-end tubes, flow cells with a set path length, standard ground joints (14/20 to 29/42), and copies of discontinued parts.
- Tell us. Send the idea, sketch, sample or drawing, with temperature, chemicals and quantity if known.
- Engineering review. We confirm feasibility, grade and build route, and flag risks.
- Quotation. Price and lead time within 24 business hours. Simpler parts 7–14 days, complex assemblies 3–6 weeks.
- Make, check, ship. Annealed, inspected under ISO 9001 and packed for export.
Is Quartz Glass the Right Material for Your Process?
Fused silica runs to 1200°C continuous (1300°C short-term), passes deep UV in optical grades and resists hot mineral acids, but it is brittle. Numbers are in the technical specifications and the quartz vs borosilicate comparison.
Good fit
- Service above borosilicate limits, up to 1200°C
- No metal or alkali pick-up from the vessel
- Light below about 300 nm must pass
- Hot HCl, HNO₃, H₂SO₄, aqua regia or solvents
Ask us first
- Pressure or vacuum (wall is calculated per drawing)
- Molten alkali salts or fluxes
- Long tubes running unsupported
- Surfaces heated above about 1150°C after handling
Wrong material
- Hydrofluoric acid
- Hot concentrated phosphoric acid
- Hot strong alkalis such as KOH or NaOH
- Continuous service above about 1200°C, or heavy impact
Why Buyers Work with FGQuartz
FGQuartz is a manufacturer, not a trader. Melting, drawing, diamond machining, flame work, polishing and annealing all happen in our 15,000 m² ISO 9001 plant in Lianyungang, so a drawing never passes between workshops.
- Standard and custom parts from one supplier, so a furnace set can match in one material system.
- Start with a single prototype, then repeat or scale.
- If quartz is wrong for your chemistry or temperature, we tell you before you pay.
- 500+ customers in 40+ countries, with export packing and documentation.

Frequently Asked Questions
Is there a minimum order quantity?
No. We make single prototypes as well as production runs.
How fast will I get a quote?
Within 24 business hours of receiving your drawing, sketch, sample or description.
What are your lead times?
Simpler parts take 7–14 days and complex assemblies 3–6 weeks. We confirm the exact lead time in the quotation.
What can I send you to start?
A CAD file (DXF, STEP, IGES or PDF), a hand sketch, photos, a worn sample, or a plain description of what the part must do. Add temperature, chemicals and quantity if you know them.
Will quartz glass work with my chemicals?
It resists hot mineral acids such as HCl, HNO₃ and H₂SO₄. It is the wrong material for hydrofluoric acid, hot concentrated phosphoric acid and hot strong alkalis such as KOH or NaOH. If you are unsure, ask us before you order.
Do you ship internationally?
Yes. We supply customers in 40+ countries, with export packing and documentation.
