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.
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.
The lowest melting point is of course - 39 0C.
Solids have varying temperatures at which they melt into a liquid. Experiment with chocolate, wax or butter, record, which has the lowest and highest temperature when it melts.
The lowest temperature on Jupiter is 234.43 degrees

The melting point depends on the solder. The lowest I've seen is 395F.

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.
The boiling temperature of copper is 2 835 K.
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).

Helium with a melting point of -272.905
With the exception of Helium all elements can be solids should the temperature and pressure be appropriate. Please see the related link for elements sorted in descending order of their melting points.
Pluto is not the lowest temperature. The lowest temperature possible is −273.15°C. Pluto's coldest temperature is about −233°C.
