Working in heavy industry provided me with the means (money) to get a higher education. It also taught me as much as university did. This story is taken from a time after I finished my studies, returning to pay off the last of my university debt and to save for an extended journey I was planning.
In the Reverb Furnace the first job on the rung was slag launderman. In some ways, it was my favourite job on the Reverb. But it was not a job to hold onto for a long time. If you were permanently placed on the Reverb or the Fuming Plant crew, you had to go up the hierarchy. In my father’s time there wasn’t much movement and you could hold one position for many years. When I was there, things moved much faster. This was good in some ways. You got ahead more quickly, and that meant higher wages as well as leaving behind a job faster that maybe didn’t appeal to you so much. It also meant you had less time to learn each job, and there were some occasions when it was important to have more than just superficial knowledge and experience.
There were always 3 shifts a day. The dayshift was 7:30 – 3:30, afternoons 3:30 – 11:30 and graveyard 11:30 – 7:30. We changed the shift every two weeks, just about when you are starting to get used to it. If somebody left or transferred to another department, all the people below that position would move up, filling in the gaps created along the way. That meant I might be moved to the next job up on the ladder but perhaps with a different crew on another shift. For me it was a good way to get to know everyone. It’s easy to complain about the last shift leaving the worst things for you to deal with when you come on, but sometimes you’re on the other end of things, and you might find they aren’t exactly what they seem. Especially when you work a double shift on occasion.
Actually I worked a lot of those. It paid time and a half and was like a week’s wages for ‘only’ two full days’ work. I was young and had no obligations like taking care of a family so it was a good way to save up for extra money needed during the winter at university or for saving up for my BIG TRIP later on. I once worked 24 hours, two successive overtime shifts, but not as slag launderman. It was as a bricklayer’s helper. They were short of men and needed to get one of the furnaces operational fast, so I agreed. The bricklayer knew what to do and I helped him prepare the mortar, break off edges of bricks, handed them over to him, and even sometimes laid a few layers myself. We had to rebuild part of the inside of that furnace and it was pretty warm inside there, not being all that long since the last time it was being used. When it was physically possible to enter and begin restoring that troublesome area, we did.
I only did it once, and that was enough. I had done much harder physical labour before, but 24 hours inside an oven can take a lot out of you, even with an occasional break.
I went through the ranks, soon becoming a ‘switcher’, or did they call it ‘3rd operator’? Either way it was still quite low as far as prestige and responsibility went. Besides helping the esteemed tappers prepare the mud and a lot of menial chores around the furnaces, my primary job was to accompany those tappers whenever there was a ‘tap’.
When informed by the first operator, usually through a loud incessant buzzer accompanied by a rotating red alarm light, the tapping crew would immediately head for the furnace. Down one level below, the slag trains would already be in place. The idea was to ‘tap’ the furnace, opening up a hole to drain its molten contents down a launder and into one of the pots connected to a train. When one pot was filled to the desired level, the switch would be thrown and a different pot on a different train would begin to fill. Meanwhile that first train would move to line up the next of 4 pots.
The tapper would get his lance ready, maybe some three or four meters long, and thrust the heavy iron bar with a sharpened edge directly into a small plugged-up hole. It would take a number of hard thrusts and with any luck, the bar would break through. If not, then a long series of options laid before us, like one person holding the bar in place and another swinging a sledge hammer hard onto the bar’s head. If that didn’t work, jackhammering was the next step, and a bigger crowd started gathering round until a solution was found.

Eventually, hopefully sooner more than later, there would be a hole into the furnace, and from its own pressure, many tons of hot fiery liquid metal would start shooting through that hole.
The launder guided its journey down into the waiting pot below. The switcher had to have an idea of what was in the furnace but more importantly, he based his decisions on what he saw happening in the pot. There were a couple of little porthole windows enabling him to see what was going into the pot and its reactions. He could see the velocity and the volume building up. You didn’t have a computer or calculator. You had to work out how high to fill that pot before switching over to the other train. If you switched too frequently you got everyone angry, including the train drivers who had to keep lining up all the time. If you waited too long, you had a nasty spill on your hands and if you did that more than once, your reputation would get even nastier. No-one wanted to work on the same shift as a bad switcher. It meant many extra hard back-breaking hours jackhammering the external crusts of the magma, trying to clean the track below.
You were trained. A little. Somebody would be with you the first shift or so, and the tappers would look over from time to time, maybe giving you some tips, but they often had their hands full. So you looked and you thought and you tried to apply everything you thought you remembered and understood. When you were still green, it’s an anxious time. You watch the force of that molten rock spewing forth. You look at the colours. They tell you a lot about the temperature and the composition. You see where and how and when the crust forms around the edges inside that pot. You get an idea of the density of that liquid. And you see the line around the inside of that pot rising, rising, rising. When? Now? No, give it a little more. It seems to be fine. Remember that after the fourth pot is full, the train needs a little more time to later line up the first again. Okay, now.
