flysocal24 Posted November 24, 2020 Share Posted November 24, 2020 Thank you, Sir. It does have a slight ring when tapped while sitting on my bench. I have to weigh it also. I plan on a spark test but as you suggest I need to see what spark patterns I should expect. Quote Link to comment Share on other sites More sharing options...

swedefiddle Posted November 25, 2020 Share Posted November 25, 2020 Good Morning, Don't give it a 'REAL' Spark Test. Why burn it??? LOL Neil Quote Link to comment Share on other sites More sharing options...
ThomasPowers Posted November 25, 2020 Share Posted November 25, 2020 Now way back when I once melted some cast iron in my forge. I was reading one of the old guesses about how they made damascus steel back in medieval times. They suggested that they had layered cast iron and steel to get it. So I made up a billet of a high grade cast iron---thin plates from a bathtub with some mild steel and heated it up towards welding temp. The cast iron layers melted and when I tried to weld the billet; big globs of molten cast iron were squeezed out flying through the air until they suddenly burst into sparks! (I now know that they were decarbing in flight and burst into sparks when they became steel and started burning.) Experimental archaeology can be fun when you try out some of the "theoretical" stuff they published 100 years ago! Quote Link to comment Share on other sites More sharing options...
