Description

Trustleaf Aluminium Sulphate (Al2(SO4)3) is a versatile, iron-free crystalline powder designed for a wide range of applications in home, garden, and industrial settings. This high-quality alum serves as an effective water purifier by causing impurities to coagulate, allowing them to settle or be filtered out easily. It is an essential tool for anyone maintaining water features or ponds. For gardeners and horticulturists, this product offers a practical way to manage soil pH. By reducing soil acidity, it can be used to change the color of your hydrangeas. It is also suitable for use in organic agriculture and horticulture. Beyond the garden, this crystalline alum functions as a reliable mordant in textile dyeing and printing, helping pigments adhere to clothing fibers. It also finds use in paper-making and as a jar sterilizer. Whether you need a water treatment solution or a chemical for textile work, this 500g bag provides a pure, effective option.
