3. Lead: ( Types of Metals ) Lead could be a soft, heavy, malleable metal with a comparatively lower melting point and low enduringness. It will face up to corrosion from wet and plenty of acids. Lead is wide utilized in power cables, batteries, building construction and fastening. 4. Zinc: ( Types of Metals )
What is coal slag? Coal slag, also known as boiler slag, is a recycled product produced by coal-burning plants. When coal is "fired" at over 2,500 degrees, it melts and produces a by-product called slag. The slag is cooled through a process called vitrification which causes it to solidify and form sharp, angular granules in a variety of sizes.

Scrape all you can free, wash the Portland off well, place in a crucible, place crucible in a furnace which will attain a heat of 2000 F. When Lead and Gold alloy are liquid, pour into a cone mold, decanting the Pb/Au alloy, leaving what still solid Iron is left in the crucible. Chip off any remaining slag. 1000 grams is a lot to cupel all at once.
