Soil solarization. Follow these four steps to solarize your soil: cultivate and remove plant matter; level and smooth the soil; irrigate; and lay a clear tarp on the soil surface for 4 to 8 weeks, depending on local conditions.
Die casting is a manufacturing process that can produce geometrically complex metal parts through the use of reusable molds, called dies. The die casting process involves the use of a furnace, metal, die casting machine, and die. The metal, typically a non-ferrous alloy such as aluminum or zinc, is melted in the furnace and then injected into the dies in the die casting machine.
Brass is a metal that consists of both copper and zinc. Bronze is a metal that consists of copper and tin. Bronze is the most popular metal for cast metal sculptures or bronze sculptures. Common bronze alloys often have the unusual and very desirable property of expanding slightly just before they set, thus filling the finest details of a mold.
