Plate Glass Materials
Soda-Lime Glass (Annealed or Tempered)
Soda-lime is the most common glass type, valued for its versatility and cost-effectiveness. It is widely used in architectural glazing, protective panels, and general-purpose applications. When tempered, it gains additional strength and safety performance, making it ideal where impact resistance is required.

  • Stock Thickness Range: 1/8″ up to ¾″+
  • Advantages: Inexpensive, adaptable, readily available.
Borosilicate Glass 3.3 (Annealed or Heat Strengthened)
Borosilicate is the backbone of scientific and industrial glassware, recognized for its excellent chemical durability, thermal shock resistance, and mechanical stability. More optically clear than soda-lime, borosilicate maintains performance in demanding environments such as laboratories, process systems, and high-temperature assemblies.
  • Stock Thickness Range: 0.7 mm up to 1-½″+
  • Advantages: Resistant to rapid temperature changes, superior clarity, highly durable.

Fused Quartz (GE124)
Fused quartz is engineered for the most extreme applications. Cut directly from boules, it withstands extremely high heat and exhibits outstanding thermal shock resistance. Its superior UV transmission and chemical resistance make it essential in optics, semiconductor manufacturing, and high-purity chemical processes.
