Phosphorus and Iron Spikes Analysis

The video follows Craig Tester, Alex Lagina, and Charles Barkhaus as they visit St. Mary's University to have Dr. Christa Brosseau analyze 18th-century iron spikes. The analysis, using a scanning electron microscope, reveals phosphorus in the spikes, suggesting they predate 1840. This finding could indicate the spikes' origin and link to the Oak Island treasure. The video concludes with discussions on the historical context of phosphorus in iron and potential future research directions.

• Nitrogen

• Carbon

Why is phosphorus significant in the context of the iron spikes?

• It makes the metal more flexible

• It makes the metal brittle

• It strengthens the metal

• It changes the color of the metal

What historical practice began in the mid-19th century related to phosphorus?

• Adding phosphorus to iron for strength

• Extracting phosphorus from iron for manufacturing

• Using phosphorus as a fuel

What does the presence of phosphorus in the spikes suggest about their origin?

• They are definitely from Asia

• They were made in the 20th century

• They might be from Britain or northern Europe

• They are from South America

What is the potential significance of the spikes being original?

• They could provide clues about the builders of the money pit
