WITHERITE

Miscellaneous

• Family: None
• Region: None
• Mined At: Unspecified
• Raw Mineral: Yes
• Generic: No

Notes

(Richard Willis)

Mineral, ideal form of BaCO₃ and typical analysis of BaO 77.7%, CO₂ 22.3%
Hardness: 3.3 Density: 4.3 Soluble in HCl and HNO₃
Often known simply as “barium carbonate”, the principal mineral source for BaO, a major flux and colorant. Can be used in place of calcium carbonate with no visible difference in clays or glazes, particularly when fusion temperature needs lowering.
