Gypsum is a naturally occurring mineral mined in numerous locations throughout the world. Gypsum is chemically known as calcium sulphate dihydrate or CaSO4.2H2O

Synthetic Gypsum is chemically manufactured gypsum and is generally considered a by-product that is created during various manufacturing, industrial or chemical processes. It is important to note that synthetic gypsum and natural gypsum have essentially the same chemical compositions, both consisting predominantly of calcium sulfate dehydrate or CaSO4 2H2O.

Abrasive blasting is ideal for preparing any type of surface prior to repainting or re-coating, and it effectively removes old layers of paint and industrial coatings, and can also be used to remove corrosion, rust and other contaminants from many different types of materials and surfaces. Common high quality recyclable abrasives include coal slag, copper slag, and other metallic grit

Salt (Na Cl) is a crystalline solid and found in the cubic form along with the seawater as the salty water evaporates due to heat energy of sun and wind. It is white in color and dissolves in water. The size of the salt crystal varies, but is typically ¼” minus, with NaCl content of 99%. Rock salt – sodium chloride (Na CL) is an industry standard for road deicing due to its ability to melt ice at temperatures down to its eutectic point of -6° F (-21° C).
