The glass industry relies heavily on high-purity raw materials to ensure clarity, strength, and chemical stability in its final products. At Gimpex, we supply top-grade silica sand, feldspar, and limestone — essential ingredients in the manufacturing of container glass, flat glass, specialty glass, and fiberglass. These minerals contribute to the melting behaviour, durability, and transparency of the glass.

Our quartz and feldspar are processed to meet stringent iron content thresholds, ensuring minimal colour distortion — a key requirement in optical and architectural glass. Limestone acts as a stabiliser, improving resistance to weathering and chemical corrosion. With consistent particle size distribution and customised grades, we help glass manufacturers optimise furnace performance and reduce energy consumption.

As global demand for energy-efficient buildings, solar panels, and lightweight packaging continues to rise, Gimpex is committed to supporting the glass industry with sustainable, high-purity mineral inputs that enhance product quality and production efficiency.
