Other examples of metals and ceramics that can withstand lava's temperature include; titanium, iridium, iron alloys, osmium, nickel alloys, aluminum oxide, mullite, and silicon nitride.
Flexi Says: Although extremophile bacteria have been found living in some harsh environments, the temperature of molten lava is high enough to break the chemical bonds that hold organic molecules together. Thus, nothing known to science can live in lava.
A curious variety of animals nourish themselves off chemicals released by an eruption. Despite the conditions, their populations thrive and grow. There are shrimp and crabs that feed off the nutrients in hardened lava.
First, although lava at 2,000 degrees F can melt many materials in our trash – including food scraps, paper, plastics, glass and some metals – it's not hot enough to melt many other common materials, including steel, nickel and iron.
To put it simply, a diamond cannot melt in lava, because the melting point of a diamond is around 4500 °C (at a pressure of 100 kilobars) and lava can only be as hot as about 1200 °C.

When lava erupts beneath a glacier or flows over snow and ice, meltwater from the ice and snow can result in far-reaching lahars. If it enters a body of water or water enters a lava tube, the water may boil violently and cause an explosive shower of molten spatter over a wide area.
We conclude that the optimal heat generated by lava at 2,190°F cannot melt the tungsten because of its high melting point. Other examples of metals and ceramics that can withstand lava's temperature include; titanium, iridium, iron alloys, osmium, nickel alloys, aluminum oxide, mullite, and silicon nitride.
The answer—quite surprisingly—is yes, they can! Not only do sharks survive in underwater volcanoes, but it seems that they thrive there. In fact, Kavachi's entire marine community appears to be accustomed to its acidic, blistering hot water and frequent eruptions.
The volcano sharks are a small group of different species of sharks living, and thriving in a hostile environment. The extremely hot and acidic waters surround the Kavachi: a highly active submarine volcano. In fact, they even live right inside the caldera of the volcano. Read on to learn what we know so far.
Lava won't kill you if it briefly touches you. You would get a nasty burn, but unless you fell in and couldn't get out, you wouldn't die. With prolonged contact, the amount of lava "coverage" and the length of time it was in contact with your skin would be important factors in how severe your injuries would be!
You would never fall into a lava lake the way you would a swimming pool, the molten rock is much more dense, so you would simply land on it, sink a little, and be burned."
First, lava is more than three times denser than water; because humans are made mostly of water, it's three times denser than us, too. The laws of physics therefore dictate that we will float on its surface, not sink.
While your lungs would almost undoubtedly be irrevocably charred from the hot air above the lava (assuming relatively static air conditions over the lava), it takes about 80 seconds for the average human to fall unconscious from lack of oxygen, and I highly doubt your body will last that long.
Is lava hotter than the Sun? While lava is still intensely hot, it is not hotter than the Sun. On average, lava can range between 1,300 to 2,200 degrees Fahrenheit, depending on its location. It's safe to say the sun at all parts is much hotter than lava.
Answer and Explanation: Magma is hotter than lava, depending on how recently the lava reached the surface and if the magma and lava are from the same magma chamber below the volcano.
Actual lava is red-orange in color, given its temperature. Truly-blue lava would require temperatures of at least 6,000 °C (10,830 °F), which is much higher than any lava can naturally achieve on the surface of the Earth.
In fact, as it spills out onto Earth's surface as lava, the runny rock's temperature is only a little lower than the hottest part of a candle flame: about 1200 °C. On the other hand, a big blob of lava contains many more bouncing particles than a small candle flame, so it has a lot more heat energy.
Rocks that cool quickly, especially the outer layers of a flow, are primarily composed of glass particles and tiny mafic minerals. This is why the outer surface of a flow is black.
Dipping your hand into molten rock won't kill you instantly, but it will give you severe, painful burns — “the kind that destroy nerve endings and boil subcutaneous fat,” says David Damby, a research chemist at the USGS Volcano Science Center, in an email to The Verge.
Concrete has a melting point of about 1,500 degrees Celsius (2,700 degrees Fahrenheit), while lava reaches a piddly 871 degrees Celsius (1,600 degrees Fahrenheit). Pour enough concrete into a vent and you would theoretically be able to block it. But that doesn't mean it's a good idea.
Less dense things rise above more dense things, so if you attempt to replicate the actions of the authorities in a particularly egregious 1997 Hollywood movie and build a wall of concrete around a massive lava flow, it won't stop it – the blocks will float on top of it, heat up and begin to melt.
