There is some confusion surrounding the production of the first rubber stamp. In America, Charles Goodyear discovered the process by which rubber is cured in 1844, while he was experimenting in his kitchen. He dropped a mixture of rubber and sulphur on to a hot stove and found that it was still flexible the next day. The process was dubbed vulcanisation after Vulcan, the Roman god of fire.
The birth of the rubber stamp was closely entwined with early dentistry. Vulcanised rubber, set in plaster moulds, was used to make cost-effective denture bases. Dentists had their own round vulcanisers, called 'dental pots', which would be used, eventually, to manufacture the first rubber stamps.
In 1866 James C. Woodruff started experimenting with a vulcaniser, trying to make some letter moulds. He asked his uncle, who was a dentist, for help and advice and after additional experiments with the 'dental pot', the first quality rubber stamps were created. Some of the rubber stamp companies formed in 1880 are still in business today. The rubber stamps we are familiar with are those found in banks and offices, such as the mechanical date stamp, often found in Post Offices.
The first picture stamps came in the form of educational stamps. German artist Kurt Schwatting, as early as 1919, used artistic stamps in his collages. The home of 'art stamps', as they are often called, is California, where they have been popular for over sixteen years, and there are specialist shops just selling art stamps. With the increase in workshops and demonstrations over the last few years, the craft has grown tremendously.
