Eutectics are well known oxide mixes that melt at very low temperatures. Many frits are identified as being a particular eutectic. By knowing critical mixtures of oxides that melt at the lowest possible temperatures you can:
-Optimize your formulation to possibly reduce flux content (thereby reducing thermal expansion)
-Reduce firing temperature (thereby reducing energy costs)
-Avoid formulations that sit on the edge of a eutectic that might exhibit variable melting behaviors
-Find formulations to create super-low melting behavior

The lowest temperature at which a mix of oxides will melt and form a eutectic reaction (simultaneous crystallization). Only mixtures of some oxides will do this. The temperature is often an anomaly, that is, it is much lower than the melting temperatures of only slightly different mixtures. Lead-tin...
