"Through tireless toil, I have studied our predecessors, and solved one of the great Hogwarts mysteries. Some wanted to keep us safe from the world; Some wanted to keep the world safe from us. Some wanted to amass power inside the school, no matter the danger. Some had the plan to keep that power in the right hands. Each Common Room hides a house sigil. Only a student true of their house can find the sigil."

—The text engraved in the beaker in runes.^[src]

The Beaker of Bartholomew was a glass container owned by Bartholomew, a former Potions Master of Hogwarts School of Witchcraft and Wizardry. Bartholomew engraved his discoveries about the fabled Cursed Vaults and the motives of those who sought to unlock their secrets in runes, and left it behind in the Potions Classroom.^[1]

History

Centuries later, during the 1986–1987 school year,^[2] the Beaker of Bartholomew was retrieved from the Potions Classroom by Jacob's sibling with the guidance of the Gryffindor House Ghost, Sir Nicholas de Mimsy-Porpington. The former subsequently used it for their own research on the vaults while searching for their lost brother. Although the ghost began reading the engravings on the beaker, they were interrupted by Caretaker Argus Filch, who was suspicious of what they were doing there. The two quickly managed to verbally oust him from the classroom, finishing the read.^[1]

Behind the scenes

Despite the name of the object with "beaker" generally referring to a cylindrical container with a flat bottom, in Harry Potter: Hogwarts Mystery, the Beaker of Bartholomew resembles more like a volumetric flask, which is usually pear-shaped with a flat bottom.
