History
Forerunners
The forerunners of the chemistry set were 17th century books on "natural magick", "which all excellent wise men do admit and embrace, and worship with great applause; neither is there any thing more highly esteemed, or better thought of, by men of learning." Authors such as

included chemical magic tricks and scientific puzzles along with more serious topics.
The earliest chemistry sets were developed in the 18th century in England and Germany to teach chemistry to adults. In 1791, ''Description of a portable chest of chemistry : or, Complete collection of chemical tests for the use of chemists, physicians, mineralogists, metallurgists, scientific artists, manufacturers, farmers, and the cultivators of natural philosophy'' by
Johann Friedrich August Göttling
Johann Friedrich August Göttling (5 June 1753 – 1 September 1809) was a notable German chemist.
Gottling developed and sold chemical assay kits and studied processes for extracting sugar from beetsFriedrich Accum of London, England also sold portable chemistry sets and materials to refill them. Primarily used for training druggists and medical students, they could also be carried and used in the field.
Scientific kits also attracted well-educated members of the upper class who enjoyed experimenting and demonstrating their results.

John J. Porter and his brother Harold Mitchell Porter began The Porter Chemical Company in 1914. Their initial purpose was to sell packaged chemicals, but they soon introduced kits. John researched the experiments, while Harold wrote the instruction manuals. Their earliest toys, under the "Chemcraft" trademark, were "chemical magic" sets, selling for less than one dollar (or about $25 in 2017). By the 1920s, they sold six different sets, the largest of which sold for $25 (or about $320 in 2017). Their range of toys broadened throughout the 1930s. In the 1950s it was possible to buy toys featuring radioactive ores, such as the "

, in spite of restrictions on materials. Robert Treat Johnson, noting the number of chemistry students at Yale whose interest in the science began with a chemistry set, argued the production of chemistry sets was a "patriotic duty."
Toy companies promoted chemistry sets through advertising campaigns, the "Chemcraft Chemist Club" and its accompanying "Chemcraft Science Magazine", comic books, and essay contests such as Porter's "Why I want to be a scientist". The goal of attracting students to a potential career in chemistry was often explicit in the sets' naming and promotion. Chemistry sets may have been the first American toys marketed toward parents with the goal of "improving" children for success in later life.
The target market for chemistry sets was almost exclusively boys, deemed "young men of science." However, during the 1950s, Gilbert introduced a set targeting girls. They sold the set in an attractive pink box, but the set identified girls as "laboratory assistants" or "lab technicians," not scientists.

Well-known chemistry sets from the United Kingdom include the 1960s and 1970s sets by Thomas Salter Science (produced in Scotland) and later Salter Science, then the "MERIT" sets through the 1970s and 1980s. Dekkertoys created a range of sets which were similar, complete with glass test tubes of dry chemicals.
