Why Use a Mirrored Surface for "Lines"?

Why do people line and rail their powdered drugs on a slab of mirror? Is it practical or just cliché; what's wrong with other surfaces, like agate geode, glass, or marble.

Mortar and Pestle Materials?

I've been looking at Mortar/pesstle sets. I intend to use mine with herbs (herbalist), not for cooking.
What material is best? I need a good material that won't leave any grains or peices from the mortar in the finished product. (That will give me a pure product with little impurities.)
Marble, granite, porcelain, agate? I was thinking marble. I heard it's the best for pharmacy, but then I heard agate was the best if you were looking for purity. What do you use and why?
