The next thing on Aramis' list was a cauldron. So therefore, a good place to go was the Cauldron Shop. He entered the Shop, that had shelves of cauldrons of all different colours. He looked on his list, he had to get a pewter cauldron or a black cauldron. There were plenty of them. But what size did he have to get? The list said size 2. That was relatively small. He walked over and picked up a black, cast iron cauldron. It wasn't massively heavy, although it certainly wasn't light as a feather. He took it to the counter.

"Excuse me, could you plese tell me how much these cauldrons are?" he asked.

"That would be 5 Galleons." He replied.

Aramis stopped to think. If they were only 5 Galleons, He could afford to buy another one, a smaller one for his altar. After all he was going to have to set one up in Hogwarts.

"Could I have another black cauldron, a size smaller?"

After buying the two cauldrons, and handing over 10 Galleons, he walked out back into the big wide wizarding world.
