It was unfortunate, but perhaps not surprising, that despite the fact they were in a potions class, the first three answers were all spells, two of which were variants on the same charm. Noble nodded at Eiji. “Good points, yes. The permanency can be both a desirable trait, and an unfortunate one. Though as Daisy mentioned, there’s a less long-term version should you be unsure if you want to be able to unstick the item.” He gave a slight smile at the Hufflepuff, before moving on to Nettie…who had an interesting suggestion indeed. “Nice answer, Nettie. There’s some people that argue to should be classified as a charm, but yes, it can be a little finicky to reverse and handle. Best used at a distance.”
Jade’s hand was the next to go up, and Noble nodded as he let his hands rest together behind his back. “Not just Muggle, actually. There’s magical types of glue too.” Two of which were in the cauldrons at the front of class, giving they were the topic of today’s lesson. “For the most part, as you say, it’s easy to use. But you do have to select the right glue for the job.” He looked to Archer next, and wasn’t necessarily surprised by her slightly out of the box answer. “There are. A less damaging solution would be the paperclip. But staples are a quick and convenient way to join pieces of paper. Some of you might consider them to keep your homework together.” Hint hint.
Drewett’s answer was one of the ones he’d expected to come out first; the Ravenclaw had no need to sound so nervous. “Yes, Drewett. Spellotape can be used for all sorts of odd jobs, even when magic isn’t appropriate. And it can be removed, though will damage the surface of some items.” Something that would definitely damage the items if attempting to pull them back apart was Lucas’ answer. “Definitely. Like glue, as Jade mentioned, just the stronger, more permanent version. And very easy to stick your fingers together with.” Hopefully they remembered that in their next activity.
And the last hand up was Cordelia’s. “Yes. Pins and nails are methods of fastening that have been used for hundreds of years. And depending on the material they’re used with, can be easily removable or a more permanent way of joining things together.” He glanced over the rest of class now, in case anyone had anything else to add. Noble didn’t mind Dorian staying quiet, better than saying a stupid answer after all, but the Potions professor did have a problem with the look on Nina’s face. “Something you would like to share with the group, Nina?” He eyed her a moment, before moving on with the lesson.
“Today we’re going to look at some different potions that can be used to stick things together. On the front desk are five cauldrons. I want you to take a sample of each in a clear cup, and then, using the descriptions on page 365 of your textbook, carefully identify which is which. There are wooden stirrers and scrap parchment for you to use in your investigations. Please cover the floor where you’re working with some newspaper before starting, wear gloves, and be very careful what you touch.” Better safe than sorry, especially since one of the options was StuckOnGlu, and he would prefer not to have to send people to the hospital wing...or for that matter, explain to the Headmaster why his duelling arena had students and random pieces of parchment stuck to it. “You may begin.”

Usually white in colour, and reasonably viscous. Dries clear and shiny, though can be slow to do so if used in large quantities. Can make paper and parchment wrinkle as it dries.
Basic sticking solution
A basic potion for sticking lightweight materials such as parchment together. Has a few minutes of working time whilst the parchment can be repositioned. The bond weakens over time.
Spellotape
A cellophane adhesive tape covered in a sticking solution. Removable on some surfaces without a trace.
StuckOnGlu
A well known brand of magical superglue, it dries when the materials come into contact with little working time for adjustment. Creates a strong and lasting bond.
Gripping solution
Transparent viscous liquid that dries clear and shiny. Cannot be removed from the first item on with it is applied. Grips onto other objects, essentially increasing the friction between them, but be can easily repositioned as many times as desired. Often used as a fastening for waterproof cloaks, or where muggles might use velcro.
