The range between onset and clear point is recorded and then the average of the two is the melting point, or, one can give the range, e.g. : 135-136℃.
Minerals with higher melting points will increase the overall melting point of a rock. Conversely, minerals with lower melting points will decrease the overall melting point. The composition and proportion of minerals in a rock will determine its melting point.
Melting point: the temperature at which a solid become a liquid. Boiling point: the temperature at which a liquid become a gas.
The three elements that have lower melting points than calcium (which has a melting point of about 842°C) are sodium (melting point 97.8°C), potassium (melting point 63.5°C), and magnesium (melting point 650°C). Sodium and potassium are alkali metals, known for their low melting points, while magnesium, though a metal, also has a relatively lower melting point compared to calcium.
The melting point can help a scientist identify a substance.
Tellurium (Te) Melting points: 722.66 K, 449.51 °C, 841.12 °F Boiling points: 1261 K, 988 °C, 1810 °F
The melting point of 3727 is not clear as it is provided without a unit of measurement. Typically, melting points are given in degrees Celsius or Fahrenheit. If referring to degrees Celsius, a melting point of 3727 degrees Celsius would represent a very high temperature.
Minerals with higher melting points will increase the overall melting point of a rock. Conversely, minerals with lower melting points will decrease the overall melting point. The composition and proportion of minerals in a rock will determine its melting point.

the melting points differ to differant solids
Ionic compounds have a higher melting point.
That depends on the solid: ice has a very low melting point, lard and butter have low melting points, chocolate has a relatively low melting point, wax has an intermediate melting point, lead has a high melting point, iron has a very high melting point, tungsten has an extremely high melting point.

Boiling Point 27.07 K Melting Point 24.56 K
Ionic compounds have a higher melting point.
helium cannot exist as solid and thus has no melting point
Pure substances have very specific melting (and boiling) points. Assuming the substance is pure you could measure the melting point and compare it to a known database of melting points.
False, all minerals DO NOT have the same melting point
