The manufacture of metal alloys is ubiquitous, yet infrequently discussed in high school coursework as concepts related to them are often too complex or abstract for beginning science students. However, earlier introduction to metallurgy in classroom settings could promote interest in practical applications of chemistry, physics, and geology due to the demonstrable significance of materials in daily use. Elemental metals with low melting points such as bismuth, zinc and tin are melted down, mixed at various percent compositions, and allowed to solidify.
