cut glass is very smooth and polished, whereas pressed glass is made in a mold and will present two seam lines at opposing sides of the glass. Often, but not always, it will show some "chill marks" as slight rippling on the flat planes.

Pressed Glass is used for many different glass products. Such as Domestic and Decorative purposes. It's used for paper weights, glass ware, and vases to name a few items.
