Frequently Asked Questions

What is the purity level of your quartz products?

Our standard fused quartz products are manufactured with 99.99% SiO₂ purity, meeting JGS1 and JGS2 optical standards for laboratory and industrial use.

Can you manufacture custom quartz components?

Yes, we offer full OEM and custom fabrication services. Provide your drawings or specifications and we will manufacture to your exact requirements.

What industries use your quartz glass products?

Our products are used in semiconductor manufacturing, solar energy, laboratory research, LED production, high-temperature furnaces, and chemical processing.

Do you provide fire-polished quartz tubes?

Yes, all our quartz tubes undergo fire-polishing to remove micro-cracks and enhance mechanical strength and surface smoothness.

What is the difference between clear and milky quartz?

Clear quartz is transparent and used for optical applications. Milky (opaque) quartz diffuses infrared radiation and is ideal for heating elements.
