Oday Hammadi

Small variations in pressure generally have inconsequential effect upon a melting point. The chemical nature of the pressure medium, however, cannot be overlooked. Reaction between the environmental gas and the metal standard and container materials could alter the determined melting point significantly.

Luma M. Ahmed

I agree with Dr. Oday, the effect of pressure is slight for solid materials.....

Manuel Schnabel

Agree with prior posts. Pressure has large effect on boiling point, not necessarily on melting point.
