The way to cast aluminum with plaster molds

Aluminum can be cast into nearly any shape resulting in castings of sculptures, art pieces or even tools. Although casting aluminum involves very high heat and molten metal, it can be done at home with relatively little equipment.
Many people around the world cast aluminum, and many useful items have been produced by home casting. With experience and practice, you could build sculptures such as full-scale busts, or large machine tools such as a lathe or a mill
1.Carve or sculpt the wax into the shape you want to cast in aluminum. The process used for casting aluminum with plaster molds is called lost wax casting. In this process, a model of the desired object is made of wax and coated in plaster. After the plaster has dried, the wax is melted out of the mold and replaced with aluminum.
2.Mix the plaster of Paris with water in the 5-gallon bucket. Be sure to mix enough plaster so that the model will be covered by at least 2 inches of plaster when placed in the bucket.
3.Tie a length of string to the end of each sprue and vent. Tie the other end of each length of string to a dowel rod. Submerge the wax model in the bucket of plaster. Be sure not to submerge the sprues and vents -- you will pour metal into these. Allow the plaster to dry overnight.
4.Add more charcoal to the flower pot and place the crucible in the fire. Use tongs to keep the crucible level in the fire. After the crucible has warmed, add scrap aluminum to the crucible. Blow on the fire with the bellows. Aluminum has a melting point of over 1,200 degrees Fahrenheit, so the fire needs to be at least that temperature.
5.Remove the crucible from the fire with tongs after you have melted enough aluminum. Pour the melted aluminum into the mold quickly. Fill the mold as completely as possible. When casting aluminum, it's better to have too much molten metal than not enough.
