During the 19th century, tea was sold by all kinds of shops, even chemists and grocers. Loose tea leaves were stored in large chests, which were weighed and given to customers in bags. Certain unscrupulous shopkeepers would artificially extend their supply of tea by adding sawdust and other materials to the chests. Before long, tea producers such as Horniman's and the Mazawattee Tea Company started packing their produce in lead boxes to stop this kind of tampering. The perforated tea bag was introduced to the public in 1904.
