Ultra-pure potassium nitrate (>99.6%) is an essential flux for enhancing the artistic quality and industrial precision of ceramics, specially designed for those pursuing perfect visual effects. In high-temperature glaze formulations, its extremely low chloride content can eliminate pinholes, turbidity and discoloration, while its thermal stability ensures decomposition control, thereby optimizing melt viscosity.
Potassium nitrate is a strong oxidizing agent that can ensure the complete combustion of organic binders, releasing the true pigment potential of metal oxide colorants and presenting them with bright and consistent tones. Its unique decomposition property can improve the flow dynamics of the glaze, creating a smooth glassy surface with excellent depth and clarity by minimizing bubble retention.
For high-end ceramics, porcelain and luxurious art applications where aesthetics are the top priority, potassium nitrate can provide a flawless luster – transforming functional surfaces into brilliant masterpieces through science-driven perfection.
