How MGS Leads the Way in High-Purity
Fused Quartz Fabrication

Since 1989, Machined Glass Specialists (MGS) has been a pioneer in custom fused quartz, silica, and borosilicate fabrication. With the surge in demand for ultra-pure quartz components in semiconductors, photonics, solar, and optics, MGS blends decades of experience with cutting-edge fabrication for unmatched precision.

1. Why Fused Quartz Matters in High-Tech Industries

Fused quartz—or fused silica—is nearly pure silicon dioxide (SiO₂), prized for its extreme thermal stability, chemical resistance, and optical clarity across UV to IR ranges. It’s essential in semiconductor photolithography, UV optics, fiber optics, and solar applications due to its ultra-low thermal expansion and minimal impurities—qualities that MGS ensures in every part.

2. Advanced Fusion Techniques: Flame, Plasma & Electric Arc

    MGS utilizes state-of-the-art fusion methods:

    • Flame fusion (Type II/III): Ideal for optical-grade quartz rods and tubes

    • Plasma fusion (Type IV): Produces ultra-high purity, low-OH glass suited for semiconductor optics 

    • Electric arc fusion: Delivers bubble-rich glass for specialized industrial applications

    These methods let MGS tailor quartz qualities like OH content, clarity, and thermal properties to your industry’s specific needs.
