How much video can you record on a 64 GB iPhone 12? I expect the last thing to melt would be left over quartz although it would first transform to tridymite and then cristobalite before melting finally melting. As Wikipedia tells us, it consists of $\ce{Al2O3}$ ($14.42\%$) (alumina) whose melting point is $\pu{2072^\circ C}$, and $\ce{SiO2}$ ($72.04\%$) (silica) whose melting point is $\pu{1713^\circ C}$. Granite is a very hard rock formed from the crystallization of magma deep underground. To learn more, see our tips on writing great answers.

Numbering the equations in LaTeX with minipage and eqnarray, My undergraduate thesis project is a failure and I don't know what to do. It is a hard, crystalline rock, which is very resistant to erosion. This was supposed to occur across a migrating front. Colors of the stone that are more readily available, such as white or black, will typically be less expensive than a color like red. Fractional crystallisation serves to reduce a melt in iron, magnesium, titanium, calcium and sodium, and enrich the melt in potassium and silicon – alkali feldspar (rich in potassium) and quartz (SiO2), are two of the defining constituents of granite. Use MathJax to format equations. Magmas will evolve to the eutectic because of igneous differentiation, or because they represent low degrees of partial melting. So does it soften to modelling clay (or at least partially soft, modelable via tools structure) at $\sim\pu{2000^\circ C}$, or does it stay hard and why? (counting names in directories).
