    sand addition is not unusual when wet reclaiming silicates. Dry reclaiming sodium silicate sand is rather impractical because the metal casting process temperatures completely dehydrate and vitrify the coating. The vitrified binder, after it has cooled to room temperature, could be so much stronger than it was originally that

    Chemically bonded sand consists of silica sand and chemical binder that is activated by a catalyst. Commonly, they are used in core making where high strengths are necessary to withstand the heat of molten metal, but also in mold making. Silica sand is thoroughly mixed with the chemicals; a catalyst initiates the reaction that cures and hardens the mass

    Silica sand, also known as quartz sand, white sand, or industrial sand, is made up of two main elements: silica and oxygen. Specifically, silica sand is made up of silicon dioxide (SiO2). The most common form of SiO2 is quartz – a chemically inert and relatively hard mineral. SiO2 grades at a 7 out of 10 on Mohs hardness scale, making it ideal for use as filtration media and abrasive blasting sands
