This is a small Minecraft mod which makes glass blocks drop glass shards.
You randomly get glass shards by breaking glass or glass panes. The chance is configurable, and glass panes only give 3/8 as much as glass blocks.
You can smelt glass shards in a furnace to get your glass back.
Stained glass and panes drop stained glass shards. They can be recolored using dyes, or you can use Gunpowder to remove the color.
