Alum: The Ancient Roman Wonder Mineral
By Jade Dawes
Alum, a natural mineral salt, was vital to the ancient Romans. It played a key role in their medicine, industry, and daily life. This #TimeTravelTuesday, let’s explore the history of alum and its many uses in ancient Rome!
Alum in Roman Medicine
The Romans were advanced in their medical practices. Alum, known for its astringent properties, was a crucial part of their treatments. It was used to tighten tissues and stop bleeding, making it essential for treating soldiers’ wounds. Quick healing was vital in ancient times when the risk of infection was high.
Alum in Roman Industry
Alum was also important in Rome’s textile industry. It acted as a mordant, helping dyes stick to fabrics. This kept the colours of Roman clothes and tapestries vibrant. Rich colours were a sign of wealth and status, making alum a valuable trade item. The long-lasting colours of Roman fabrics show how effective alum was in dyeing.
