But 10,000 dead sea snails 29A you just one gram of purple dye, as well as a very bad smell! This 30C purple dye was called the "Tyrian Purple", and it was the preferred 31A of emperors. In 16th-century England, purple was 32D for the king's family members. Queen Elizabeth I's clothes were purple, but ordinary people were not allowed to 33A the colour.
In 1856, William Perkin, an 18-year-old 34B student, noticed something strange while doing an experiment. The chemicals(化学品) he used to clean his instruments 35B with the chemicals he used in his experiment and produced a bright purple colour. This 36C led Perkin to start a company using this chemical mixture to make purple dye. The dye was much 37C than the sea snail dye. Thanks to Perkin, now anyone can afford purple clothes.
