Michel,
In your photos your show glass and crucible as raw materials. What exactly is "crucible" ? -------a crucible is a ceramic container which holds the molten metal in the furnace. Why do you put green glass in your forging process ? ---------the glass is a flux which bonds with the oxides and removes them from the metal so it can melt and be free of contamination...borax is too aggressive and will eat the crucible. You utilize steel powder. Don't you loose a lot of this material before it is molten by oxidizing it and really burning it ? ------the crucible is covered (cosed system) and the glass is the flux so there is very little loss What is the advantage of utilizing steel powder versus a piece of steel ? ---the steel is a modern metal powder of known chemistry so I can get a certain type of steel when I cam finished.
