Glass Fleck - Before the indie flakie craze, there were clear or tonal flakes (not glitter) in a jelly or crelly base that our nail community referred to as glass flecks because they looked like glass. The base was so packed, they covered VNL fairly well in just a few coats. Don't take my word for it though, All Lacquered Up has an entire post discussing these at her blog.
Gel Polish - Typically requires UV light to cure and is said to last up to two weeks. Some brands have used this term differently to describe a regular nail polish.
