Sodium tetraborate
This is 99% pure 5 Mol borax used with casein to make paint and tempera emulsions, neutralize the acidity of gum arabic in watercolors, and others. Borax (sodium borate or sodium tetraborate dodecahydrate, Na2B4O7·10H2O) is an important boron compound. It is a soft white many-sided crystal that dissolves easily in water. If left exposed to dry air, it slowly loses its water of hydration and becomes the white chalky mineral tincalconite (Na2B4O7·5H2O) or sodium tetraborate pentahydrate.
