What makes a good wand?

In general, the guiding philosophy behind this world is a sort of magical realism or quasi-scientific approach. I'm wary of having anything just be 'magical' without explanation. There are certain materials that make for good casting foci (wands, staffs, spellswords, etc). Generally, you want something that's light, not brittle, and doesn't burn or have a low melting point.
