Have you ever considered who actually built Hogwarts? Godric was off fighting wars, Rowena was always researching something or other, and except for some secretive sewer plans, Salazar was far too important do be bother with mundane matters like construction. This left Helga with the job. How else would the Hufflepuffs get the best spot for their common room, right by the kitchens?
This teapot is the same style used by this Hufflepuff for his Herbology experiments (read: tea) at home. With the finest muggle craftsmanship, the laser mesh infuser basket allows but little particulate matter into the brew, and the sturdy construction and low center of gravity make for good every day use.
