There is just that scratching-on-the-board feel when I screw the metal cap back onto the glass shaker. Also, it will break if I happen to drop it.

What is behind the glass factor?

Lets say, why not plastic? It's cheaper to make and doesn't break. Does it have to do with taste? I don't notice a difference in taste between salt stored in glass and plastic.

Glass is used as it is non-reactive to salt. The same applies for most plastics.

Iron based metals for the most part are reactive so that is why they aren't used.

We have a wooden salt shaker to match our wooden pepper grinder. You just have to look around for them. More garage sales than department stores, I'd say.

go into any McD's and its in plastic so no issue there w glass vs plastic. i imagine people like the weight of glass better, feels less cheap than plastic.

we have ceramics that you fill from the bottom and stoppered with a flex plastic plug.
