Strategic Feldspar Supply for Industrial Kilns

Feldspar serves as the primary fluxing agent in ceramic and glass formulations, acting as a catalyst to lower the eutectic temperature of the batch. In ceramic production, our Potash Feldspar begins to melt at approximately 1150°C, creating a persistent liquid phase that fills the interstitial spaces between quartz and clay particles.

This process, known as vitrification, is essential for eliminating porosity and creating a dense, waterproof structure. The potash variety specifically contributes to the development of a structural “skeleton” during firing, preventing the slump or deformation of large-scale industrial insulators. In the glass industry, our Soda Feldspar provides the necessary alumina (Al2O3) to improve chemical durability, thermal shock resistance, and inhibition of devitrification. By stabilizing the molten glass, it ensures a smoother forming process and superior clarity in the final product.

CGST Cahaya operates as a strategic link in the mineral supply chain, leveraging Malaysia’s prime position at Port Klang to facilitate fast and cost-effective shipping across Southeast Asia and the global market. We provide end-to-end transparency with full COA documentation for every shipment, ensuring batch-to-batch consistency that industrial engineers can rely on.

To meet diverse production requirements, we offer highly flexible packaging solutions, ranging from standard 25kg moisture-resistant bags to 1.5MT UV-stabilized Jumbo bags for automated bulk-feeding systems. Our logistics team ensures that every ton of Feldspar remains pure and uncontaminated from processing to delivery, managing the entire transit chain to prevent moisture absorption and mineral degradation.
