A Naturalist's Discoveries

Plants and Alum

One of Thomas Chaloner's clever observations was about plants. He noticed that certain types of plants grew only in places where minerals needed to form alum were present in the soil. This helped him realize that the rock used to make alum was very common in areas around his cousin's estate in Guisborough. This area is now part of Redcar and Cleveland.

The Alum Industry

Thomas Chaloner's cousin, Sir Thomas Chaloner, became very involved in developing the alum industry in England. Thomas the naturalist played a part in helping his cousin with this important work.

Big Business Deals

Later, around 1606-1607, Sir Thomas Chaloner (the courtier) formed a business partnership. He worked with people like Sir David Foulis to get a special agreement. This agreement gave them the only right to make alum in northern England for 31 years. Eventually, the English Crown, which means the royal government, took over these businesses.
