As Ewan started to reply, Noble nodded in agreement and moved to the blackboard to write down the key points. It was always good to have something for the students to refer back to, but these days, it was more important than ever. “Indeed,” Noble said, “The two subjects are intimately entwined, in part because of the materials at their cores: metals.” He noted both strong links with alchemy and extracting metals from their ores as bullet points under the title he’d written before class started.

The next hands up were Noah and Naya’s. Noble nodded at the two Gryffindors “Metals having different properties or behaviours,” Noble paraphrased, “…that is definitely something to keep in mind as we go into the next activity.” As was Missa’s answer. “They are. Metals have many different uses, in both our world and theirs.” Though they tended to go about their manufacturing processes a little differently. He added different properties of metals and uses of metals to his list.

Returning his gaze the class, he looked over Claudine sitting quietly at the back, and over to the next raised hand. Which was Nettie’s…and the Ravenclaw was clearly struggling for an answer. “Sort of,” he replied. “Whilst some metals are pure, others, such as the alloys Noah mentioned, are made of a mixture of elements. This is something we’ll get into more next lesson.” It was a little out of scope for today, if they wanted to get to the practical bit.

“An art form indeed,” Noble agreed with Islay. Despite the, er, situational difficulties this year, the Gryffindor was really coming into her own in his classes. He might even have been impressed. “And as you say, a relatively old one with all sorts of applications.”

And somewhat in contrast to that well thought out answer... “Metal-lurgy” he repeated to Phoebe. “Though, yes, some people are allergic to metals. You might have seen jewellery, particularly earrings, marked as being nickel free for that reason.” As for the green skin? “What you’re talking about, Berndette, is actually the remnants of a chemical reaction between the metal and your skin, or something on your skin, such as sunscreen. Though the resultant green substance can also cause typical allergy symptoms like itchiness or redness.”

Valencia’s answer was short and sweet, and Noble nodded. “It is,” he said, adding the study of metal and its properties directly under the headed. “And you’re quite right, the name was originally applied to the process of working with metal…but was later taken to be used more generally for the study of this purpose.”. Etymology was fun; he covered some of that in his Latin course too.

Was he surprised at Eiji’s silence? A little. He knew the Slytherin knew this, and could (and would) speak lyrically on the subject. But he also saw the eagerness dancing in the boy’s eyes, which perhaps suggested he wanted to just do already. They would be soon enough.

“Yes, it’s something to do with metal,” Noble replied to Tom, unable to keep the exasperation from his voice, even if the boy’s memory loss wasn’t his fault. They all had it these days. But really, how many times had he written metal on the blackboard now? Grumble.

He could probably do with more coffee.

Thankfully, Heath gave a much better answer to finish on. “Correct. Chemical metallurgy considers how metals react with things, how to extract them when they have reacted, and various other chemical properties…whereas physical metallurgy concerns the mechanistic properties and how they perform in different scenarios. Considering both will serve you well in our first activity.” An activity it was time to start.

He moved to his second blackboard, flipping it over to reveal a pre-written list of metals. “Here is a list of metals, and around the room are several objects.” Of course, usually he would have revealed them with a flick of his wand, but instead he now started to move around the room to remove the cloths manually. “Using the information in your textbooks, as well as anything else you know about them, I want you to link the metals to the objects they are used for. In particular, think about what properties – chemical or physical - make them good for that purpose?”
