There are many materials that can withstand these temperatures: from metals such as (nickel alloys, iron alloys, tungsten and molybdenum alloys, even though these two might have oxidation issues, iridium, osmium, titanium, etc) to ceramics (silicon nitride, aluminum oxide, mullite, zirconia, etc).
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.
Wood is the most common example of this. Unlike ice or chocolate, wood cannot melt because the combustion temperature is lower than the melting point, a fire would start before the material could change phase to “liquid” wood.
You can't burn pure water, which is why we use it to put out fires instead of starting them. You can, however, break it down into hydrogen and oxygen by putting energy into it, in the form of an electric current.
The fact that active volcanoes produce gold is not that surprising, Dr. Noble said. Significant quantities of gold are also being found along mid-ocean ridges, where so-called "black smokers" emit magma from beneath the ocean floor. Such spots are loaded with minerals, he said.
Oxygen is not flammable, but it can cause other materials that burn to ignite more easily and to burn far more rapidly. The result is that a fire involving oxygen can appear explosive-like.
All types of milk, when in liquid form, are not flammable. They will not ignite, mostly due to high water content. However, dry, powdered milk can catch fire easily, and in some cases, even explode. Overall, milk is not much of a fire hazard, but when it comes to powder milk products, things change.
So how is it that diamonds can be found among us? The answer lies in rare and unusual volcanoes called kimberlites. These deeply-seated volcanic eruptions can sometimes pick up diamonds, along with other minerals and rock fragments, and blast them to the top.
Finding gold in your backyard is unlikely unless you live in an area known for gold production, but it is worth a try. You will need to choose where in your yard to look for gold. Gold is an extremely dense element and will most generally be found on bedrock or in stream beds where it was deposited by the current.
Inside of the peel is a special oil called D-Limonene that is quite flammable. What reason could an orange have for harboring a fiery fluid in its skin? If the orange is eaten and then pooped out elsewhere, it can grow into a nice successful orange tree and produce oranges of its own.

If you breathed pure oxygen, the energy from your food would be released all at once. Oxygen radicals harm the fats, protein and DNA in your body. This damages your eyes so you can't see properly, and your lungs, so you can't breathe normally. So breathing pure oxygen is quite dangerous.
It may be hard to believe, but oxygen can also be dangerous. The dangers are fire and explosion. Pure oxygen, at high pressure, such as from a cylinder, can react violently with common materials such as oil and grease. Other materials may catch fire spontaneously.
Soils Associated with Gold Deposits. By far, the best-known type of soil which may indicate the presence of gold is known as “black sand.” Black sands are certainly not proof of the existence of nearby gold, only that the soil has a lot of minerals and heavy metals, one of which is gold.
About 244,000 metric tons of gold has been discovered to date (187,000 metric tons historically produced plus current underground reserves of 57,000 metric tons).
Not really. Magma is the molten rock that lies several kilometres below the Earth's surface. It contains many minerals that we want, but in very dilute form. It's better to let nature concentrate them for us before we try to mine them.
