Our Melt Cups are a new design for Thermal Analysis that provides a more accurate measurement with a non-boil quality that allows quick filling of the cup and more consistency in analysis. Other models use water-glass or hydrated sodium silicate to hold the Tellurium in place. This is what causes the boiling and spitting when those cups are filled. The spitting of iron back out of the cup makes the cup difficult to properly fill and takes longer, or the cup is left only partially full. A partially filled cup means the thermocouple is no longer in the center of heat which can further skew the analysis. The boiling in other cups reduces the Carbon and Silicon content, much like “green-poling” a furnace does. Because our Melt Cups can be completely filled, the thermocouple is positioned in the middle of the “heat zone”, giving your foundry the most accurate answers and more consistent results.

We offer Melt Cups with Tellurium (for Iron Chemistry) and without Tellurium (for Microstructure).
