Miller chose the 1692 Salem witch trials as his setting, but the work is really an allegorical protest against the McCarthy anti-Communist "witch-hunts" of the early 1950s. In the story, Elizabeth Proctor fires servant Abigail Williams after she finds out Abigail had an affair with her husband. In response, Abigail accuses Elizabeth of witchcraft. She stands trial and is acquitted, but then another girl accuses her husband, John, and as he refuses to turn in others, he is killed, along with the old comic figure, Giles Corey. Also notable: Judge Hathorne is a direct ancestor of the author Nathaniel Hawthorne.Bunsen burnerUsed to heat substances in labring standholds funnels, wire gauze above tablewire gauzeused to support a container (such as a beaker or flask) during heatingclay triangleused to hold a crucible while the crucible is heatedSparkerUsed to light a Bunsen burner flameScoopulaused for transferring dry chemicalswatch glassglass; used to cover an evaporating dish or beakerevaporating dishliquids are heated over a flame so that they evaporate, leaving a solid residuefilter funnelUsed with filter paper to filter substancesstuckunable to movestirring rodUsed for stirring chemicalsPipetteA glass or transparent plastic tube used to accurately measure small amounts of liquidthermometerAn instrument used to measure temperaturean elastic band
