• Sand casting: Casters moisten or oil molding sand, also known as foundry sand and then shape it into molds into which they pour molten material. This type of sand must be able to withstand high temperatures and pressure, allow gases to escape, have a uniform, small grain size and be non-reactive with metals.
• Sand castles: Shaping sand into castles or other miniature buildings is a popular beach activity.
• Sandbags: These protect against floods and gun fire. The inexpensive bags are easy to transport when empty, and unskilled volunteers can quickly fill them with local sand in emergencies.
• Sandblasting: Graded sand serves as an abrasive in cleaning, preparing, and polishing.
