Wood’s metal fusible alloy is an alloy of bismuth, lead, tin, and cadmium that melts well below the temperature of boiling water.  Onion’s metal and Rose’s metal are also low melting alloys that melt in boiling water.  Because these are low melting alloys, they can be adjusted in a teaching laboratory setting, through the addition of tin, or lead, or bismuth, all while the alloy is in the melt.  We will discuss how such alloys can be made, and how the adjustment of such metal alloys can be connected to weight percentages, molarity, and other concepts normally seen in a college, freshmen-level general chemistry course.
