Although I don't own a 2450, I have yet to see a flatbed scanner that uses plastic, and I really doubt any company would use it. Besides that plastic is very hard to produce at the optical quality required for a scanner, it is more expensive than glass, also. It may sound like plastic if it is anchored or damped around the edges. The best way to check is on a day when the room is cool or cold, and the scanner has been off for a long period, touch the surface with your finger. If it feels cooler than your finger, it is very probably glass; glass is a good heat conductor, and pulls heat from your finger and therefore feels cool. If it feels "neutral" or the temperature of your finger, it could be plastic, as plastic is more thermally insulative and therefore tends to not take warmth away from a warmer source.
