This infographic from Alan's Factory Outlet explores the science of melting points, as well as the freezing points, and the temperatures that are required to melt eighty well-known elements, substances, and metal alloys. The melting point determines when a substance will change from a solid to a liquid state, and while the freezing point is the same temperature it will cause the reverse reaction to occur where a liquid becomes a solid.
Some of these naturally occurring materials can require thousands of degrees worth of heat to reach this point. Sterling Silver must reach a temperature of 1,640°F to change from a solid to a liquid, while Quartz’s melting point is almost double that at 3,038°F.
Although neither come close to the melting point of Tantalum Carbide, a whopping 6,960°F! On the other end of the spectrum, Hydrogen has the lowest melting point at a cold -434°F, close to the -458°F temperature of the Boomerang Nebula.
