The pit is sill full of charcoal, rain is coming our way...I would like to exit the iron making process by using up all remnants of ore and charcoal. If the rain is robust. I may give steel making a shot. Making steel is a bit trickier than cast iron as steel making requires slag management. 
 

 

 

This run is not to be due to other priorities.

I had the opportunity to forge out some steel recently made…indirectly related to the topic here.             

I have spent a lot of time experimenting with various  ingot carbon content and still want to do two more tests before my temporary crucible furnace is demolished. I find all this very exiting as it c

The two photos added are a look at a reduction of thickness by a factor of 10. If the bar had still been in one piece it would be 40” long. I am not too exited about the pattern as the dendritic look

I found this article the other day, and this seemed to be the most appropriate thread in which to put it, as it is about Konasamudram. The short version is, in 2018 a guy found 60 ingots and a bunch of crucible fragments.

Unless I did not see the complete article above ...I would love to have seen some data on the microstructure and the composition of those ingots. This topic is very much alive for me. I am currently melting with a taller crucible the flatter lens crucibles are on the way. I will post some pictures as soon as this computer allows me to.

 

Below are some recent microstructures, using a narrower taller crucible

I do not have too many options left to change the resulting pattern …the main variable I can still tweak is the cooling rate. That is where I will start….should be resuming melting in 2 weeks.

Thank you Alan.   This steel was cast iron ( bloomery cast iron ) and wrought iron ( no alloys). The next sequence will be 100% bloomery material made with local magnetite ore. That will be "Sole Steel" made in the Paramecium Forge.
