"Melting" is a change of state from solid to liquid and not strictly something that can be done by the addition of chemicals. The only way you're going to melt a rock is to add heat.
Or you could dissolve the rock using chemicals. But this means the rock is now part of a solution of other chemicals...getting a rock back out of that is going to be nigh-impossible.
But for such things, we can look around us. Acid erosion dissolves rocks every day, and that's just acid rain...which is a generic acid aqueous solution name.
So...get yourself some concentrated acid. H2SO4 would probably make a good job of it.
Metamorphic rock is less likely to melt compared to igneous and sedimentary rocks due to its high temperature and pressure resistance. This resistance is due to the mineral composition and structure developed during the rock's formation.
The temperature needed to melt rock depends on its composition. On average, rocks require temperatures of 600-1,300 degrees Celsius to melt. However, some types of rock, like granite, may require temperatures well above 1,300 degrees Celsius to melt completely.
The three main factors that control whether or not a rock will melt are temperature, pressure, and the presence of fluids (such as water or gases). Increasing temperature and decreasing pressure are the most common ways to induce melting in rocks, while the presence of fluids can lower the melting point of certain minerals within the rock.
If a rock gets hot enough, it can undergo physical and chemical changes. Depending on the temperature, rocks can melt, undergo metamorphism, or break down into different minerals. Ultimately, it will depend on the type of rock and the intensity of the heat.
Pressure can increase the melting point of rock because higher pressures result in a higher melting point. However, if the rock is subjected to extremely high pressure without a corresponding increase in temperature, it may deform or undergo metamorphism rather than melting.
The rock will melt.
No. If it did then it would melt in your hand. Rock candy is made mostly of sucrose, which does not melt but breaks down at 367 degrees Fahrenheit.
Rock exposed to very high temperature and pressure will soften or melt.
If the temperature is too high, the rock will melt into magma and form igneous rock instead of metamorphic rock. Metamorphic rocks form under high pressure and temperature conditions, but if the temperature becomes too high, the rock will not be able to maintain its solid state and will melt.

Because the Himalayas are a mountain range, made of rock. The temperature is far too low to melt rock.
Metamorphic rock is less likely to melt compared to igneous and sedimentary rocks due to its high temperature and pressure resistance. This resistance is due to the mineral composition and structure developed during the rock's formation.
The two main factors that affect the temperature at which rocks melt are the composition of the rock and the pressure acting on it. Different minerals have different melting points, so the composition of the rock will determine its melting temperature. Additionally, pressure can increase or decrease the melting temperature of rocks, with higher pressure generally increasing melting temperature and lower pressure decreasing it.
When fluids such as water combine with rock, the composition of the rock changes, which lowers the melting point of the rock enough to melt it.
A combination of increased temperature, a decrease in confining pressure or addition of volatiles can all act to cause rock to melt.
