Lesson Nine: Glass to Sand Shield Study Guide

Chapter 10

When glass is in small shards, it becomes a type of sand. This spell is mostly used as a shield during combat. For example, the late Albus Dumbledore used this transformation spell to protect Harry Potter & himself from Voldemort at the Ministry of Magic.


This transfiguration spell was created by Miss Miriam Portfender in 1884. She was doing research for spells that could help you in combat.

Incantation: Contrita Specularma (CON-tree-ta spek-u-LARH-mah)
Wand Movement: Point wand at the glass
Concentration/Willpower: Low

Fun Facts
Some suggests that this spell is a transformation, while others believe the glass shatters.
In Professor Penrose's Auror Training, a duel was won for resourceful use of the spell.
The Reductor Curse is good for protecting others in combat, but needs a stronger amount of willpower.
A thing that can go wrong is that the spell is only half done; the glass is shattered but cannot be described as sand.
