Frit Melting Range (C) - MLRG

This test procedure was employed in the Foresight Ceramic Database and now is available for those having an account at Insight-Live.com. Accumulating test data using the variables defined in these procedures enables us to create tools that enable you to compare the physical properties of materials and recipes.


This refers to the range at which a glassy material softens and finally melts (crystalline materials melt at a definite temperature, glasses do not). Frit manufacturers quote Fusion temperature and Flow temperatures, this could be considered that range, namely, from where it starts to melt to where it begins to flow.

  • (Glossary) Boron Frit

    This term is very generic, referring of course to frits that contain boron. Unfortunately that is 80-90% of available frits! Boron frits may have 1% boron or 50% boron. Even though the boron in the frit is no longer in the borax form it is still customary to refer to such as "borax frits". Since man...
