Glass Fragments OR&R's Marine Debris Program

Glass fragments are pieces of larger glass items that cannot be identified, or are less than 50% of the original item. If glass fragments have been in the environment for long periods of time, they may become weathered and the edges may smooth out and they may have a frosty appearance (e.g. sea glass). Newly fragmented glass pieces are likely sharp, so take care in picking up these items (use gloves or scooper to remove sharp pieces of glass).
