  • Varieties of garnet minerals

    The most famous type of garnet stone is pyrope (flaming). This is the "oldest of garnets", with a dense red color, similar to the grain of an edible garnet. Pyrope has a variety called rhodolite - a stone of dense pink or pink-purple color, which sometimes has the alexandrite effect and is used in...

Can water burn?

It’s known that water consists of atoms of molecules of oxygen and hydrogen. Since any compound with oxygen indicates the ability of the substance to burn, water is no exception. Thus, water has a surprising property of already "burnt out" compound.
