Mg# indictes the level of evolution of a volcanic rock (e.g. Basalt) since leaving its birth place (mantle). Mg# of a primitive basalt which originates in the mantle is ~70. As the basalt undergoes evolution while passing through crust (interacting with and assimilating other rock types in the crust) the Mg# goes down from primitive number 70. For example: To get an idea of Mg#s of basalts see the below given Mg#s
Least evolved basalt (60 - 69)
Moderately evolved basalt (50 - 59)
Evolved basalt (40 - 49)
Highly evolved basalt (< 40)
The magnesium number in volcanic melts can provide information about the depth of the melting process. A higher magnesium number typically indicates a larger degree of partial melting at greater depths in the Earth's mantle, while a lower magnesium number suggests shallower melting. This parameter helps scientists understand the origin and characteristics of volcanic magmas.
Magnesium melts at a temperature of 1202 degrees Fahrenheit.
When ice is heated, it melts into water and eventually evaporates into steam as it reaches its boiling point. When magnesium is heated, it undergoes a chemical reaction with oxygen in the air to form magnesium oxide and emits a bright white light.
The element with the highest melting point is silicon. Silicon has a melting point of 1414°C, while magnesium melts at 650°C and chlorine is a gas at room temperature.
The difference in melting points between ice and magnesium oxide is primarily due to the strength and type of chemical bonds present in each compound. Ice is held together by weaker hydrogen bonds, resulting in a lower melting point compared to magnesium oxide, which has stronger ionic bonds. Additionally, magnesium oxide has a higher ionic charge and smaller ionic radius, contributing to its higher melting point.
The magnesuim melts and the reaction of it is it produces a bright light ! then when it has cooled down the magnesuim turns into magnesuim oxide because the magnesuim and oxygen attach together because the particles mix together to make magesuim oxide! :)

the heat of the stove melts the ghee very fast
These substances are chlorides of calcium, sodium and magnesium.
Volcanic magma. This melted material can rise to the Earth's surface through volcanic eruptions, creating new landforms like volcanic arcs and island chains.
When rock melts at calderas, it forms magma. This magma is then forced towards the Earth's crust as lava through volcanic eruptions.
It melts on everything when introduced to a heat source

Magnesium is a solid in it's natural state on Earth. It melts at 1,202 degrees Fahrenheit, at which point it is a liquid. It boils away at 1,994 degrees Fahrenheit, at which point it is a gas.
Rich in magnesium and iron due to their origin from ultramafic mantle rock. They are usually less viscous compared to melts formed from other types of rock. The composition of these magmas can vary depending on the degree of partial melting and the specific mantle source.
When, for various reasons, rock from the mantle melts, it sometimes moves to the Earth's surface through weak spots in the crust, releasing heat, gasses, and rock--a volcanic eruption
