A hydrated crystal is a crystal with water molecules bonded to its ions. Although it contains water, it is still a solid. It is created from a highly ionic substance that crystallizes from a water solution.Know More
Although hydrated crystals are solids, the water molecules can be removed through the crystal lattice by heating. Heating occasionally causes hydrated crystals to shatter in the process of removing the water molecules. If the crystal remains intact, the heating process forms an anhydrous crystal, which means "without water." Hydrated crystals generally change color once they become anhydrous.

The main difference between quartz crystal and glass is that glass does not have a crystalline structure. Glass is also made with additives that quartz crystal does not contain.Full Answer >
Igneous rocks that are allowed to cool more slowly form larger crystals, while igneous rocks that cool quickly form smaller crystals. It is simply a matter of time. The longer it takes for magma to cool, the more time is allowed for the crystals to form.Full Answer >
Porphyritic rock is a texture of igneous rock with two distinctly different crystal sizes due to two periods of cooling occurring at different rates. Larger crystals are called phenocrysts, while the smaller grains are known as groundmass or matrix.Full Answer >
The Mayo Clinic lists a number of ways to help prevent and minimize the effects of varicose veins during pregnancy, including elevating the legs, changing positions frequently, keeping weight gain under control, staying hydrated to prevent constipation and wearing support pantyhose. These methods help support healthy blood flow from the legs to the heart and prevent unnecessary added pressure on the blood vessels in the lower body.Full Answer >
