Floo Powder

Floo powder is a glittery, silver powder used by witches and wizards to travel through the Floo Network. The Network connects most wizarding households and buildings. This powder was invented in the 13th century by Ignatia Wildsmith.

The powder turns a fireplace's flames harmless and emerald green. It is tricky to use; one must toss a handful of powder into a fireplace connected to the Floo Network, walk into the flames, and state the desired destination loudly and clearly to ensure arrival in the proper location. Otherwise, one could end a stop away which Harry did in 1992.

Transportation by Floo powder is much quicker than by broomstick, but slower than Apparition. However, unlike Apparition, one does not require a license to use Floo powder.

Molly Weasley kept her household stock of Floo powder in a flowerpot on her mantle.
