Cardboard box with removable lid; lime cardboard insert with various indentations and slits for chemicals and tools; on the bottom is a row of six amber glass bottles with lime metallic removable lids houses in rectangular indentations; the chemicals include: ammonium chloride, sodium silicate solution, sodium carbonate, boric acid, sodium salicylate, and phenolphthalein solution; to the left of the bottles is a slit for a metallic spoon; to the right of the bottles is a slit for a metallic stir rod; above the bottles on each side are slits for paper packages of litmus paper and logwood; on the top left corner of the insert are cardboard holders for plastic test tubes of sodium ferrocyanide and ferric ammonium sulfate; on the top right corner of the insert are two plastic test tubes of cobalt chloride and calcium oxide, as well as one glass test tube; set comes with instruction manuals. Chemistry sets reached their heyday in the 1950s, but production of them began in the United States during World War I. Playing with a toy chemistry set inspired many a boy to become a chemist, and not until the late 1950s were girls considered an appropriate market.</div>
