Mild steel is iron containing up to about 0.25% of carbon. The presence of the carbon makes the steel stronger and harder than pure iron. The higher the percentage of carbon, the harder the steel becomes. Mild steel is used for lots of things – nails, wire, car bodies, ship building, girders and bridges amongst others.

Keep the poultice about 1⁄4 inch (0.64 cm) thick and extend it 1 inch (2.5 cm) past the edge of the stain. 4. Cover the poultice with plastic wrap. Poultices work best the longer that they stay moist.

The limestone is heated as it moves down the kiln toward the lower end. As the preheated limestone moves through the kiln, it is “calcined” into lime. The lime is discharged from the kiln into a cooler where it is used to preheat the combustion air. Lime can either be sold as is or crushed to make hydrated lime.
