Sand wash is an irregularity in the surface of the casting resulting from the erosion of the sand mould during pouring and the contour of the erosion is formed in the surface of the final casting. Additional Information. Swell: A swell is a slight, smooth bulge usually found on vertical faces of castings, resulting from liquid metal pressure ...
· Utility Sand: Also known as fill sand, utility sand is rather coarse in texture and is a mix of white, gray, beige, tan, and brown particles. It's typically used underneath paving stones (e.g., as a base material for concrete) or even to fill holes and trenches. It compacts especially well, despite the fact that it's not processed or washed.
Procedure. Pour the sand–salt mixture into the beaker so that it just covers the base. Add about 50 cm 3 of water, or add water until the beaker is about one-fifth full. Stir the mixture gently for a few minutes. Filter the mixture into a conical flask. Pour the filtrate into an evaporating basin.
As the name implies, the Polymeric Sand is a mixture of the fine sands that are combined with polymers and other additives. Well, this sand is flexible, which makes it an ideal option for contractors and homeowners. It can be easily used as a joint filler for brick pavers. When this sand is wet, then it remains flexible.

· Sandstone Basics. Sandstone is a type of rock made from sediment — a sedimentary rock. The sediment particles are clasts, or pieces, of minerals and fragments of rock, thus sandstone is a clastic sedimentary rock. It is composed mostly of sand particles, which are of medium size; therefore, sandstone is a medium-grained clastic sedimentary rock.
· Also known as abrasive blasting, sandblasting is a surface finishing process that involves the use of a powered machine — typically an air compressor as well as a sandblasting machine — to spray abrasive particles under high pressure against a surface. It's called "sandblasting" because it blasts the surface with particles of sand.

The main reason causes cold shut casting defect is the lack of molten metal fluidity. Here are solutions to enhance the fluidity of the metal liquid: Design the gating system properly. Limit premature solidified process by increasing the pouring temperature. Use coarser sand to enhance the sand mold permeability.
· The second step in called washing. in which the slurry is washed in a log washer before it is once again further screened. The blades of the log washer churn through the slurry to remove any remaining foreign materials.
