The carbide product produced generally contains around 80–85% calcium carbide by weight. The carbide is crushed to produce small lumps that can range a few millimeters up to 50 mm. The impurities are concentrated in the finer fractions. The CaC 2 content of the product is assayed by measuring the amount of acetylene produced on hydrolysis.
