Crystals are at the centre of magic in the Blank Magic series, not because they are essential to the performance of magic but because they make its manipulation easier. The reason for this is that their internal structure, right down to the atomic level, is so regular that they emit magical particles in certain fixed directions rather than randomly from every surface like most other objects. This directionality is also superimposed on any magical energy travelling through them.
Until the nineteenth century using crystals to direct magic was confined to personal use to direct and concentrate a wizard's own magic. With the advent of much greater availability and the development of better methods of shaping them, crystals became integrated into magical objects and tools.
When performing physical magic a mage will use his or her abilities to control the particles emitted and surrounding all matter. (the first three images below) by channelling magical energy though a crystal and emitting it in a controlled direction.

Crystals are usually used by wizards to direct and concentrate their magic but they are not essential. Much magic can be performed with only the witch or wizard's own abilities. However, many less talented wizards rely on their directional properties to assist them even in everyday tasks.
The concentrating ability of a crystal is dependent upon its intrinsic chemical form and hardness.
Only natural forms of hard crystals were readily available during the early Blank Magic stories. Crystals could, of course be grown from solution (see below). Developments in crystal technology such as creating synthetic gems were starting to be used during the early twentieth century and inevitably these became of interest to those developing magical weapons.
