Slipparite
Slipparite is a rare mineral discovered in 1986, named after its discoverer, Dr. John Slippa. It is a complex borate mineral with the chemical formula Na2Ca2B5O9(OH)3. Slipparite is typically found in the form of colorless, transparent crystals or granular masses. It has a Mohs hardness of 5.5 and a specific gravity of approximately 2.8. The mineral is often associated with other borate minerals such as borax and ulexite.
Slipparite is primarily found in the Boron region of California, USA, where it occurs in evaporite deposits.
The mineral has limited commercial value due to its rarity and the fact that it is not
In summary, slipparite is a rare borate mineral with a specific chemical composition and geological origin.
