• How To Recharge Silica Gel Crystals Beyond Photo Tips

    Silica Gel absorbs moisture in the air around your camera equipment (such a material is called an adsorbent). This ensures that the area is not friendly for fungus to grow inside your camera lenses. But did you know that if you leave silica gel inside your camera bag for too long it can get saturated with moisture and actually start to give off some of that moisture later on? This could really ...

  • How is Glass Made? Science ABC

    More specifically, glass is made by heating ordinary sand (mostly composed of silicon dioxide SiO 2) until it melts and turns into a liquid. You may wonder why the same thing doesn't happen on hot days at the beach, but the answer to that is quite simple—the melting temperature that the sand needs is very high, around 1700° Celsius.

    Note that the main component of sand is silica (silicon dioxide, SiO2) an extremely hard and slowwearing substance, which may have originated from soil or volcanic eruptions a million years ago. Since no carbon is found inside silica, it cannot be carbondated. In between the sand grains, one also finds shell (calcium carbonate, CaCO3) and organic matter, which can be carbondated.
