Rock Candy Crystals free essay sample

Crystals are formed when atoms line up in patterns and solidify. There are crystals everywhere — in the form of salt, sugar, sand, diamonds, quartz, and many more! To make crystals, you need to make a very special kind of solution called a supersaturated solid solution. Here’s what that means: if you add salt by the spoonful to a cup of water, you’ll reach a point where the salt doesn’t disappear (dissolve) anymore and forms a lump at the bottom of the glass. The point at which it begins to form a lump is just past the point of saturation. If you heat up the saltwater, the lump disappears. You can now add more and more salt, until it can’t take any more (you’ll see another lump starting to form at the bottom). This is now a supersaturated solid solution. Mix in a bit of water to make the lump disappear.

If you have too much salt (or other solid) mixed in, your solution will crystallize all at the same time and you’ll get a huge rock that you can’t pull out of the jar. If you have too little salt, then you’ll wait forever for crystals to grow. Finding the right amount takes time and patience.

It is also interesting to note that Van Gogh did not paint any self portraits when he was staying in Nuenen as he had just had a major dental treatment, and at that point of time, he saw himself as a person too unpresentable to be placed in a self portrait . It was only later in Paris where he felt more like a man about town, giving him the confidence necessary to paint his self portraits, most of which were created when he felt a need for self analysis . In Van Goghs two infamous self portraits depicting his mutilated ear, which he drew after a quarrel with Gauguin, it can be seen that the second version was not a copy of the first, but instead was Va n Goghs second interpretation of his fluctuating mental condition .
