(perhaps someday we should let Apollo know that Robert has always had an equally impressive potions lab in the sub basement of his farmhouse. he based the remodeling of the st mungo's lab, when he first got the chief of staff job, on the lab he had at home. i'm not opposed to Apollo sometime accompanying Robert there if we ever have the need to do that.)
Robert skimmed the recipe again to double check the procedure. There was something ringing a bell that it merited extreme caution. Oh. There it was. It was the addition of the Sulphur. Not only did it cause a bit of a foul odor at first, but if it were not done precisely right, the Sulphur could make the whole business explode. In this potion, it was tricky business and was easy to buggar.
"Take your time, Zabini," he coached the lad gently. "You're doing very well, but don't rush it. Don't ever rush a potion. Just keep a steady hand and take your time so that you can be confident in your work.
"Me, I enjoy potions. There is the skill of potions making, simply putting them together so that they work. However, there is also the art to potions making. For the ones who are good at it, they enjoy the puzzle of it and the thrill of creating new kinds of magic. And, then again, I'm sure we both know plenty of wizards who find potions to be a gigantic pain in the arse."
He was distracted by movement in a shadowy corner near the shelf of bug jars. He had only one shelf of bug jars here--only what was necessary to make potions. The bug jars at home were a different matter.
"Continue," he told Zabini. He drew his wand, lit it, and went over to the corner. He looked down at the floor. The jar of fire ants had apparently broken at some point, and the corner was alive with fire ants. He groaned. "Ants," he uttered. "Someone let the ants out." He got a new bug jar and put a scoop of sand in it and a food enchantment and put it temporarily on the floor. "Get back in the jar, you lot," he flicked his wand at the ants.
The light of his wand pointed out to him that some of the rarer ingredients were not as fresh as they could be, and some of the shelves had dust and were starting to grow cobwebs. Ugh. Well, that meant he was going to have to get busy and clean and order new ingredients. He usually did that job alone because few people liked spending several of their shifts in the lab.
"Stop before you add the Sulphur," he said, returning to the work table. "We will do that business together because that is where most potion makers muck this one up," he said. "In this combination of ingredients, the reaction when you add the Sulphur can be a little volatile if it is not done carefully.
"One of my not-so-brilliant classmates was desperately failing potions and he thought he could do this one in his fifth year, to impress the professor to give him extra credit. Did the worst job on a potion I have ever seen in my entire life, and nearly took out the entire potions lab. Professor Slughorn was not pleased. The moral of the story? Never eat anything made of treacle while studying potions because it looks like ink on your page." While he waited for the fire ants to comply, he took a seat on one the wooden work stools a couple of steps away so to avoid making Zabini feel like Robert was hovering. This was exceptional pressure for an apprentice, he realized.
"Well, I can see where I'm going to be spending this week," Robert sighed. "I'm going to be refreshing lab ingredient stores. Some of the ingredients are things I will need to go and get. Not all of these are just routinely delivered. If you get bored, you can always come along with me to obtain some of the strange bits--if your headmaster does not mind you doing a bit of travelling with me. Your Defense Against the Dark Arts spells are up to par, aren't they?"
