Making a Sword with THERMITE!

The video tutorial by Hacksmith involves creating a sword using thermite, a chemical mixture that produces molten iron. The process begins with a comparison of red and black iron oxides, highlighting their differences in density and iron content. The tutorial then details the thermite reaction, its efficiency, and the challenges faced during the sword casting process. Adjustments are made to improve the reaction, including adding stainless steel beads. The final sword is tested on various objects, demonstrating its sharpness and strength, despite some imperfections.

What is the main difference between red and black iron oxide in thermite reactions?

• Red iron oxide is denser than black iron oxide.

• Black iron oxide contains more iron per gram than red iron oxide.

• Black iron oxide is lighter than red iron oxide.

• Red iron oxide produces more heat than black iron oxide.

What was the yield percentage of the black iron oxide thermite reaction?

• 50%

• 60%

• 43%

• 30%

Why was stainless steel added to the thermite mixture?

• To make the reaction safer.

• To reduce the amount of heat produced.

• To improve the mechanical properties of the iron.

• To increase the reaction speed.

What was the purpose of using a thin steel disc at the bottom of the crucible?

• To increase the reaction temperature.

• To separate molten steel from slag.

• To reduce the reaction time.

• To prevent the thermite from spilling.

What was the final weight of the sword made from thermite?

• 10 pounds

• 7 pounds

• 5 pounds

• 3 pounds

What was used to etch the blade of the sword?

• Acetic acid

• Sulfuric acid

• Hydrochloric acid

• Nitric acid

What was one of the challenges faced during the final sword casting attempt?

• The sword was too light.

• The molten metal escaped the mold.

• The thermite reaction was too slow.

• The mold was too small.
