] ] A chemistry set is an educational toy allowing the user (typically a teenager) to perform simple chemistry experiments. Some of the earliest chemistry sets were developed in the 18th century in England and Germany, for use in teaching. More modern chemistry sets from the 1900s were intended to be toys. The best known such sets were produced by the A. C. Gilbert Company, an early and middle 20th-century American manufacturer of educational toys. Porter Chemical Company, with the ''Chemcraft'' sets, and the Skilcraft corporation were other manufacturers. 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. The modern offerings, with a few exceptions, tend to have less in the way of chemicals and very simplified instructions. A GCSE equipment set was produced offering students better quality equipment, and there is also a more up market range of sets available from Thames & Kosmos such as the C3000 Kit.〔 〕 Several authors have noted that from the 1980s on, concerns about illegal drug production, terrorism and legal liability have led to chemistry sets becoming increasingly bland and unexciting.〔 〕 == Contents == Typical contents found in chemistry sets, including equipment and chemicals, might include: 抄文引用元・出典: フリー百科事典『 ウィキペディア（Wikipedia）』 ■ウィキペディアで「chemistry set」の詳細全文を読む スポンサード リンク
