Omega Dustless Chalk White 10 Pcs

These dust-free chalk pieces are suitable for a variety of uses including schools, colleges, offices, and households. Designed to minimise dust, they are easy to handle and help reduce the risk of respiratory issues. In agriculture, chalk—typically in the form of calcium carbonate (CaCO?) or calcium oxide (CaO)—is used to raise soil pH in acidic conditions. Chalk can also be used as an antacid in small doses. For household tips, it helps absorb grease stains before washing and can prevent silver from tarnishing by reducing moisture when stored together.
