I type igneous granites appear to arise from the melting of preexisting igneous rocks s type sedimentary granites from melted sedimentary rocks or their metamorphic equivalents in both cases.
Can granite melt.
Consequently melting and re crystalising a granite will not exactly replicate the original conditions.
Granites can be predominantly white pink or gray in color depending on their mineralogy the word granite comes from the latin granum a grain in reference to the coarse grained structure of such a completely crystalline rock.
Blueschist this is getting a bit hard.
M type mantle granites are rarer and are thought to have evolved directly from deeper melts in the mantle.
If you had a very high pressure crucible and a means of heating it you could melt marble and re crystallize it.
Loss of water in particular will make crystallisation of the melt occur at higher temperature so you are more likely to see high t minerals such as sanidine as opposed to microcline in the recrystallised melt and you may also find that.
Because of the way granite forms it possesses a special resistance to damage from heat.
Granite will not melt even from direct flame applied to it.
Subscribe ring the bell.
You need a pressure equivalent to about 20km of rock and a temperature about 400 degrees c.
Some stone surfaces particularly those with polished finishes can be scratched or etched by the acetic acid.
What granite means.
Granite ˈ ɡ r æ n ɪ t is a common type of felsic intrusive igneous rock that is granular and phaneritic in texture.
Today s we re taking a comment request and seeing if we can successfully melt lava rock and then possibly cast with it.
Please note the fact that melting point of granite is 2210 o to 2300 o f 1210 o to 1260 o celsius whereas you cook your steak at around 350 o to 450 o f 177 o to 232 o celsius.
A word of caution however.
Marble you can t melt marble at surface pressures it decomposes into calcium oxide and co2.
Students of granites classify them in three or four categories.
