How to Make an Aluminum Foundry - Backyard Scientist

The video tutorial demonstrates how to build an aluminum smelter using simple materials like Portland cement and perlite. It includes steps to mix these materials, construct a propane burner, and use the foundry to melt aluminum. The tutorial emphasizes safety and cost-effectiveness, providing a DIY approach to metalworking.

What are the two main ingredients needed to make the aluminum smelter?

• Sand and gravel

• Clay and water

• Portland cement and perlite

• Lime and gypsum

What is the recommended consistency for the concrete and perlite mixture?

• Runny like water

• Thick like chunky cookie dough

• Smooth like butter

• Dry like sand

What is the purpose of the copper tubing in the propane burner?

• To provide structural support

• To regulate the temperature

• To act as a heat insulator

• To allow propane gas to exit at high velocity

What material is suggested for use as a crucible in the smelter?

• Plastic

• Stainless steel

• Aluminum

• Glass

How long does it take for the aluminum to melt in the foundry?

• 1 hour

• 10 minutes

• 5 minutes

• 30 minutes
