Describing a mixture of two or more substances that melts and freezes at the lowest possible temperature, lower than either substance would alone.
From Greek 'eu-' (well) + 'tektos' (melted). The prefix suggests 'good melting' or easiest melting point.
Eutectic mixtures are nature's shortcuts—a eutectic alloy melts at temperatures lower than either pure metal alone, which is why ancient smiths could work bronze so much more easily than pure copper.
