Blueschist this is getting a bit hard.
Can granite melt.
If you had a very high pressure crucible and a means of heating it you could melt marble and re crystallize it.
Consequently melting and re crystalising a granite will not exactly replicate the original conditions.
Marble you can t melt marble at surface pressures it decomposes into calcium oxide and co2.
Today s we re taking a comment request and seeing if we can successfully melt lava rock and then possibly cast with 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.
Subscribe ring the bell.
A word of caution however.
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.
Strictly speaking granite is an.
Because of the way granite forms it possesses a special resistance to damage from heat.
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.
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.
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.
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.
Students of granites classify them in three or four categories.
Granite will not melt even from direct flame applied to it.
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.
