Pandermite, a calcium borate mineral, occupies a specialized space in the borates market where it’s used primarily in ceramic glazes, specialty glass formulations, and some niche flame-retardant systems. Production is typically sourced from mineral deposits where calcium borates co-occur with other borate minerals; extraction is usually through focused mine operations that either produce pandermite directly or recover it as part of a mixed-borate concentrate. Over recent years, production volumes have been modest and largely stable, reflecting that pandermite is not a mainstream feedstock but valued for particular physical and chemical properties. Its market is characterized by low liquidity and geographically dispersed demand centers, often near ceramic and specialty glass clusters.
