All the silicates are molten at about 1200°C and all are solid when cooled to about 600°C.
The melting temperature of an alloy is generally lower than the melting temperature of the highest melting temperature of all of its constituents. The eutectic melting temperature is the lowest melting temperature of an alloy system and is in fact sort of defined by that optimal set of percentages of those constituents. The next obvious question is whether there are calculation methods or approximations to determine the melting range of less than "eutectic" percentages.
The lowest melting point is of course - 39 0C.
When the temperature reaches the lowest melting point of the mineral or minerals of which the rock is made.That depends entirely on what type of rock you have, and what it's made up of. Different substances have different melting points. Igneous rock has the highest, which means they don't melt easily. You'd have to know what types of materials are in the rock and look up their respective melting points in a chemistry book, or online. There is no one single answer to your question.
A solid with weak intermolecular forces, such as those found in nonpolar molecules or small molecules, is likely to have the lowest melting point. These weak intermolecular forces are easily overcome by increasing temperature, causing the solid to melt.
W on the periodic table. the element with the highest melting/boiling point is tungsten.
Helium has the lowest melting point of all the non-metals. It melts at a temperature of -272.2 degrees Celsius.
The boiling temperature of copper is 2 835 K.

Aluminum alloy 380 has one of the lowest melting temperatures among aluminum alloys, typically around 520°C (968°F).
NaCl, common table salt, has a rather high melting point. The substance with the lowest melting point is helium. Helium has no solid phase, it melts at any temperature above absolute zero.
Mercury is the greatest exception, because it is liquid at room temperature. The metal with the next lowest melting point is gallium.
-30C(-22F) is listed as the freezing point for mineral oil. Due to viscosity (how thick the fluid is, basically), however, it's lowest useful temperature is considered to be 10C (50F).
The lowest melting point is of course - 39 0C.
The noble gases, such as helium and neon, have the lowest boiling and melting points among the elements. These elements are gases at room temperature and have very weak interatomic forces that require little energy to separate them into individual atoms.
