Suspicious sand is a fragile gravity-affected block found in various Overworld structures. They can be brushed to extract structure-dependent loot, and are a source of pottery sherds alongside suspicious gravel and trial chambers. Suspicious sand drops nothing if broken, and break if they fall from any height or are moved with a piston.

Also called silica sand or quartz sand, silica is made of silicon dioxide (SiO 2). Silicon compounds are the most significant component of the Earth's crust. Since sand is plentiful, easy to mine and relatively easy to process, it is the primary ore source of silicon. The metamorphic rock, quartzite, is another source.

Aggregate crushing is the process of breaking down the large pieces into smaller particles. Screening – different sized aggregates are required for different types of construction projects and materials – thus they need separating. Construction aggregates can also be produced from naturally occurring deposits such as sand and gravel.

Above that is a 2 in. (5 cm) layer of finer separation gravel (0.7–6 mm), and then the top layer—16 in. (40 cm) layer of sand (< 0.7 mm) that serves as the filter medium. The size of sand is very important—if it is too coarse, then you won't get good treatment of the water, but if it is too fine, the water will flow too slowly.

The sand will fall into the wheelbarrow, and the gravel will stay behind. You can discard the gravel when all the sand is gone or save it for another project, such as lining the bottom of a drainage ditch. If you want to separate the sand into coarse and fine grades, just change the screen with one that has a finer mesh.
