    River sands are the opposite. The long journey of sand from mountain tops to the river bottom wears down the corners and rounds the edges. This will make river sand of the right mineral content very long lasting and create lower amounts of dust, but will be an overall looser and deeper ride. This may be your preference and is an acceptable choice.

    Sand is smaller than gravel, but larger than silt or clay. Most sand is composed of silica, from broken down quartz crystals. Silica Sand or Manufactured manmade sands will have very sharp angular tendencies. Natural Sands will have subangular to rounded grains, because the sharp edges are river tumbled and water worn over time.

    Properties of fused silica

    Manufactured glass is a material formed when a mixture of sand, soda and lime is heated to a high temperature and stays in a molten, liquid state. Glass can be made from pure silica, but quartz glass (also referred as quartz) has a high glass transition point at around 1200°C, which makes it difficult to form into panes or bottles.
