Natural Sodium Sulfate, 50 lb Bag

Sodium sulfate is the sodium salt of sulfuric acid. Anhydrous, it is a white crystalline solid of formula Na₂SO₄
Sodium sulfate is mainly used for the manufacture of detergents and in the Kraft process of paper pulping. About two thirds of the world's production is from mirabilite, the natural mineral form of the decahydrate, and the remainder from by-products of chemical processes such as hydrochloric acid production.

Glauber's Salt:

Glauber's salt is simply sodium sulfate mixed with water. The chemical formula is 10 H₂O*Na₂SO₄. This means there are 10 water molecules per molecule of sodium sulfate. The molecular weight of water is 18 times 10 makes 180. The weight of sodium sulfate is 142. So in order to make Glauber's salt, you simply need to mix at a ratio of 180 weight in water to every 142 weight of sodium sulfate, or 180/322 = 56% water by weight to 44% sodium sulfate by weight. As a simple example, add 180 grams of water (180ml) to 142 grams of anhydrous sodium sulfate and you will have Glauber's Salt.
