The surprising life of a humble chamber pot

Sometimes, the most ordinary objects tell the most unexpected stories.

During archaeological investigations in Bristol, our archaeology and built heritage team uncovered the fragments of a large slip-decorated chamber pot, likely produced in Staffordshire and dating from the late 17th to early 18th century. Carefully reassembled, the pot now gives us a glimpse into a world where even the most unglamorous aspects of daily life had surprising value.

At first glance, the object is familiar, a domestic chamber pot, once tucked beneath a bed or kept quietly out of sight. But in the past, these vessels played a much bigger role than simple sanitation.

In fact, the contents they collected were anything but waste. Urine was an important and widely used material in early industry. The ammonia it contains made it a powerful natural detergent, useful for cleaning fabrics and removing grease. It also helped soften leather and was used in textile dyeing, where it helped colours appear brighter and more vibrant.

In some cases, the material collected in chamber pots travelled much further than the household where it was produced. During the 17th and 18th centuries, large quantities were transported to North Yorkshire, where they were used in the alum industry to create a mordant a chemical that helps dyes bind to cloth. It even had a role in the manufacture of gunpowder.

Seen through this lens, the humble chamber pot becomes something quite different – a small but vital part of an economic system linking households, craftspeople and industries.

Jeremy Bradley, Finds Officer at Civic said: “Urine wasn’t waste, it was infrastructure. Behind every Georgian townhouse, every dyed coat, every bolt of cloth, was a chamber pot.

“Finds like this remind us that archaeology is not only about monumental buildings or dramatic discoveries, it’s also about the overlooked objects that quietly supported everyday life.”

At Civic, our archaeology and built heritage specialists work across the UK to uncover and interpret these stories. From archaeological evaluations and excavations to historic environment assessments and building surveys, our team helps ensure the past is properly understood as places evolve.

Because understanding what came before is essential to shaping sustainable, resilient places for the future.
