9th bell on 85th of Winter, 513 AV The Ironworks
Ethan was spending the last few remaining bells of his shift opening up the shop for clients. He had spent the last several hours back at the blast furnace with Ros showing him how to make weapon steel. It was a present of sorts for all the hard work that Ethan had given the smith over the years. Ros’ weapon steel was known for its purity and strength, not to mention its price. Sadly Ethan also knew that it would be years before he could reproduce a bar of the stuff. Ros had directed Ethan to bring out several bars of steel for him. To the general public Ros made weapons from regular steel, or iron that had been forged over and over again, but it head impurities that made the blade weak and brittle. Weapon grade steel had several process that were done to it. First, Ethan collected a great deal of thin steel pieces and placed them all in different small pots, once the steel had melted Ros poured them out to create a thin sheet of metal and started with the explanation. “Ethan there are two things that differentiate regular steel from weapons grade steel. One is the flexibility of the steel that comes from the charcoal content that is added to the steel. The second is from the impurities in the metal. So you have helped night shift smelt down Iron Ore, what you are doing is using the coal to give the iron a little more strength, just doing this and gain experience in skimming the ore will allow you to make decent steel, but to make excellent steel you have to refine the process more.” “Every run of steel the ironworks makes, I have them pour a small coin mold for the steel bar. I take this coins and melt them and make cloth thin sheet with them. The reason why is that I want to see how they break Ethan.” Ros picked up a cooled sheet of metal and tried to bend it with his hands, the sheet bent maybe ten degrees and then broke into two. “Hmmmm, not bad. See Ethan that bend showed the steel content. By seeing how far it bends I can gauge how much charcoal I need to mix with the steel.” Ros handed him the broken piece, “Go ahead and try to bend it.” Ethan did the same as Ros, using his tough hands to bend the steel. The thin sheet gave way a little sooner than Ros’ half did. Looking at Ros he wondered what had happened. “The smaller the piece you try to break Ethan the less give it will allow. Still you could have gauged bend and came up with the figure after some practice. Now look at the broken edge of the steel.” Ethan did so. “See the little black specks? Those specks are impurities from the ore that didn’t melt or float to the bottom of the pot. The more specks inside the steel the more the steel will crumble or facture along a line. Sometime you wouldn’t be able to see those dark spots, if that is the case look at the broken end anyway, if it all looks like dark greyish circles, then the specks are spread throughout the metal and a smith tried to hide the results from you or your client. If that is true then the weapon or armor they made is likely a little bit better than a stew pot.” Ros then went over to several other thin layers of steel and repeated the process. A lot of them broke at different angles and finally he got to one that bent in half. “Ah, mild steel, this is great for armor, because through the tempering and setting process it can turn into spring steel. While its in it’s mild from you can easily hammer out the steel into the general shape that you want and then Temper the pieced by cooking it in the forge for a specific blue color.” Ros smiled at Ethan for a moment, “However, I don’t tell a smith that secret till he has master his metalsmithing and worked on a few armor pieces for me. So let’s stick with weapon’s grade steel. Mild steel has way too much carbon in it to become a weapon. The reason why its used in armor is that it will deform slightly absorbing the blow of the weapon, and then spring the energy back to the person. A weapon needs to be flexible so that it doesn’t crack under the stress of combat, but it needs to be hard enough to hold an edge during it. So weapon steel should never go over this much flex.” Ros went over to the last cooled puddle of steel and picked it up. What was different about this was that the steel seemed to bend almost thirty degrees without breaking and then spring back to straight. Whereas the mild steel had just bent and never went back into shape again. “So now that you roughly know the bending of the steel, you can figure out how much charcoal to put into the mix.” Ros went over to the thin puddle that held about half the strength that the weapon steel had done. Picking up the small bars take came with the sample steel, Ros picked out three or four bars and placed them on a scale. “Now Ethan the golden weight. I know that the charcoal needed to this steel is roughly one hundred of its weight. If the steel had been brittle so that we only had the most minor of defections I would use one fiftieth of its weight. You must be very precise about this Ethan, and that’s why it will take many trials and errors before your own understanding of the metal becomes instinctual. So never try to sale weapon’s grade steel, until testing three samples per pound of metal you make.” Ros undercovered a clay jar with small ground charcoal in it and measure the weight as carefully as he could with a scale. Once done, he loaded the charcoal and steel bars in a crucible. Lastly he took out some sand and a bucket of broken glass. “The glass will get rid of the slag or specks in the metal, but if you put too much it will interfere with the heat, its important Ethan that you know some steel can never become Weapon’s grade, so never try to sale it as such. So look again at the broken end of the steel, I see about three dark specks in the size of thumb, along with four hair line streaks, that means we need to measure out about one twentieth the weight of the steel in sand and put two thumb size glass piece in the crucible.” Ethan measured out the sand carefully with a scale, balancing the weight till it was near perfection. Pouring the sand into it and wedge two thumb size pieces, Ethan and Ros then placed the lid on it and began to surround the lid with clay. “The last secret of the weapon’s grade steel is heat. By sealing the vessel the metal is in, it will make sure that no more charcoal or coal can get into it. Additionally, we will have to bury the vessel in a coal fire for twelve hours. If we have a Volcano furnace like Sultros, we probably could do it in less time, but we don’t and until someone finds a pre-valterrian blast furnace, time and heat is the only things we have.” Ros looked away for a moment and then back at Ethan. “Anyway, twelve hours at the very least. It needs to be surround by at least one foot of coal or three feet of wood for that time. That’s why we use the big blast furnace to smelt weapon’s grade steel it’s the only vessel large enough to provide the heat.” Ethan looked at Ros for a moment and realized just how honored he was to have learned the secret of weapons grade steel. Granted he would probably spend seasons on trying to make a few bars here and there, but now that he had the recipe all he needed was practice and experience in gauging the steel stock. Ros looked at Ethan for a moment and then spoke on last time, “Now that you know, your ready to start your own shop if you like. I know you said you were coming back in a season or two, but sometimes young lads forget their way home. So go over to the counter work it for a few more bells and when you’re done, I will have your Smithing sigil.” To Ethan it was the greatest gift that anyone had ever given him. Ros approved enough of his work that he would get a seal or sigil of his own. It meant that Ethan was allowed to open up a shop if he choose to and make tools or weapons under his own sign. Ros was a master at the art, and though Ethan knew he had years to gain a fraction of the credit and understanding that Ros had of the art, it meant that Ethan was no longer an apprentice, but a smith in his own right, and he was proud. So Ethan went over to the Ironworks shop’s corner and waited for a customer to come in. |
