enough for one night [Jan. 7th, 2011|10:03 pm]
Doug Ayen
I decided to try making something out of the various experiments and some scrap, so I weighed the leavings from all but the last experiment out. Two pieces had some cast iron already in them, which I added in straight; the other, earlier experiments I weighed and added in an equal amount of cast iron scrap, along with some glass as a flux. All of it went into a No. 10 crucible, and into the crucible furnace it went, at approximately 8:15 PM. After running the furnace for about an hour, I checked, and the charge was mostly liquidus. I gave it another 20 minutes, shut it down, and am leaving it to cool overnight. If my calculations are right, this should be about 1.5% carbon, right in the sweet spot for wootz, and the traces of vanadium should assist in making a nice carbide formation, assisted by the slow cooling rate.

I did try taking a picture of the liquid metal in the crucible, but the camera just couldn't handle the light; nothing but glare. After I shut off the lights, though, I thought I had left one one accidentally, as the shop was lit quite nicely by a bright orange glow. Even though the furnace is fairly well sealed, enough light was leaking out to make it quite bright.

Way cool!

A great-uncle of mine used to work at the GE Newark Quartz plant where the made quartz crucibles for the steel and other metal-working industries.
