Our friends at Heartland Research group are having fun and discovering many important things. I know they have something going on in November so be sure and check them out at zarahemla.site to participate or donate. They truly are bringing things from the earth so in there latter days we can benefit with science ,a archaeology and research. May the Lord bless Wayne May, Kevin Price, Mike and Betty Lafontaine, Mike Baker, Melissa Tillack, John Lefgren, Jeff Green, Ryan Sorensen and many others who are moving forward with this important work.

Museum-quality replica of 4th Century Copper Alloy Arrowhead from a crystal-clear stream in the northern woods of Wisconsin. Copyright by Heartland Research Inc. Dateline: Perry, Utah Tuesday, September 21st, 2021 Without fire, it is impossible to have a civilized society. Without controlling intense heat, it’s impossible to have the advantages of metal weapons on the battlefield. On Saturday, we poured hot liquid metal. In less than a tenth of a second, we made replicas of copper alloy arrowheads formed with the same chemical assay and aerodynamic design that ancient people developed from North America. Indeed, we believe that today is the first time that anyone has cast metal alloy to make replicas of arrowheads that native Americans made more than 50 generations ago. Today we added the patina to the surface of the metal arrowhead. We used the same methods that world-class museums use when they make replicas of their famous artifacts. In early June, we started the project. We thought that with modern tools and methods, it would be easy. We were wrong. We knew that working metal requires a high level of skill and knowledge. We thought that because the ancients made their castings with charcoal-fired furnaces and with less sophisticated materials for their molds, we would easily be able to work our metal better than they did theirs. After spending thousands of dollars and hundreds of hours, we now stand in awe at the skills of the ancient people. The metal arrowheads are witnesses that the people in the Heartland of North America had exceptional talents in metalworking. They managed to get temperatures in their furnaces to 2,200 degrees Fahrenheit. They understood that by controlling different elements, they could increase the hardness of the alloy. They understood how the arrowhead’s design affected its flight as it moved through the air towards its target. They built effective molds to fix the casting of the liquid metal. They could get the hot liquid metal to flow into the molds’ cavities in less than a second. Their metal arrowheads would have had zero value in battle if they failed in these and other tasks.If there are doubters about the metallurgical knowledge of the people in the Heartland, then we ask the doubters to go into the wilderness and do what we know the ancient people did when they cast their arrowheads. We are willing to give the doubters 100 years in the wilderness to do what they need to do to get the job done. We expect that they will fail in their efforts to work the metal. Here are pictures that relate to today’s casting. Liquid Copper Alloy Casting into Mold of Arrowhead at 2,200 Degrees Fahrenheit. 4th Century Copper Alloy Arrowhead Found in a Crystal Clear Stream in the Northern Woods of Manitowish, Wisconsin . Wax Mold of 4th Century Copper Alloy Arrowhead. Wax Mold of 4th Century Copper Alloy Arrowhead with Spruce for Movement of Extremely Hot Liquid Metal into Cavity . Jewelry quality platinum cured silicone for room temperature vulcanization of master mold. Pressure injected casting wax at temperature of 180 F and 10 PSI positive pressure. Hand cutting of platinum cured silicone mold. Note irregular cut of the wall of the silicone mold for locking the two sides for making lost wax mold . Attachment of Spruce for Passage of Hot Liquid Copper Alloy into Cavity of the Arrowhead’s Mold. Casting Tree for Nine Arrowheads Attached with Spruce Gating . Mixed Dawn detergent with rubbing alcohol, ratio of 1 to 10. Solution is sprayed on the casting wax. “Surfactant” reduces air bubbles on wax molds . Mixing casting investment with water . Vacuum degassing of the casting investment . One hour set time for casting investment in flask . The casting flask is placed in burn-out oven for twelve hours at temperatures in a stepwise fashion from 250 F to 1200 F . LOST WAX PROCESS: The melting and burn-out of wax from investment flask to create the cavities for the casting of nine arrowheads . Casting flask ready for the pouring of liquid metal . Here are the total charges for creating the copper alloy. One percent of the total weight is tin. The tin doubles the hardness of the alloy . Chemical Assay of 4th Century Copper Alloy Arrowhead . Crucible for holding metal charges as heat of torch turns metal to liquid . Torch heat at 2,200 degrees Fahrenheit. Cleaning with water of the newly cast arrowheads after the breaking of the investment mold. This is the first time in 50 generations when the ancient copper alloy is used to cast arrowheads that are replicated after the artifact found in Northern Wisconsin.
