Today s we re taking a comment request and seeing if we can successfully melt lava rock and then possibly cast with it.
Can granite melt.
Blueschist this is getting a bit hard.
If you had a very high pressure crucible and a means of heating it you could melt marble and re crystallize it.
Granite ˈ ɡ r æ n ɪ t is a common type of felsic intrusive igneous rock that is granular and phaneritic in texture.
You need a pressure equivalent to about 20km of rock and a temperature about 400 degrees c.
If that s the case we have the interesting dichotomy that one can melt granite moderately easily if with a high temperature but one cannot then fuse freeze the molten product back into granite as at surface pressure it will form rhyolite instead.
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.
Granite will not melt even from direct flame applied to it.
M type mantle granites are rarer and are thought to have evolved directly from deeper melts in the mantle.
Marble you can t melt marble at surface pressures it decomposes into calcium oxide and co2.
What granite means.
A word of caution however.
Subscribe ring the bell.
Because of the way granite forms it possesses a special resistance to damage from heat.
Much gentler more environmentally friendly and safer for pets and vegetation than salt based melting agents cma is increasingly the deicer of choice for natural stone landscapes.
Paul woskov a senior research engineer at mit s plasma science and fusion center psfc is using a gyrotron a specialized radio frequency rf wave genera.
Some stone surfaces particularly those with polished finishes can be scratched or etched by the acetic acid.
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.
Strictly speaking granite is an.
Students of granites classify them in three or four categories.
