[About Raw Alum]
Raw alum [AlK(SO₄)₂・12H₂O] is a state where water is added to baked alum [AlK(SO₄)₂]. Since baked alum is hygroscopic, it absorbs moisture from the air and gradually returns to raw alum.

Raw alum is easy to handle as it dissolves easily in water. For details on its uses, you can find various information by searching alum on Google.
