Ground Ulexite Ulexite, also known as Sodium Calcium Penta-borate Octahydrate, is a white, free flowing granular material. It is a naturally occurring borate ore that is minimally processed and ground to meet manufacturing specifications for different particle sizes. Upon melting, Ulexite forms a clear melt with smooth flow properties that are ideal for particular applications.
