A poolside table is a hard place for a single flat color to work. The water throws its own blue, the tile has a tone, and one uniform shade of glass tends to fight both. This bag blends three: Aqua Blue, Caribbean Blue and Aqua Green together, so the filled surface reads with depth and variation in daylight rather than as a sheet of one color. The pieces are glass blocks at 0.75 in., chunkier than crushed shards or flat beads, which leaves visible gaps between them and lets flame come up through the bed more openly. Material is quartz sand processed into fireproof glass rated to 1112 F, holding color under sustained flame without melting or darkening, and producing no smoke or odor of its own. Ten pounds suits a smaller bowl or a top-up of an existing fill, with the recommended depth running 2 in. to 4 in. Because the blend looks right without flame, the same media works dry as a planter topping, a garden border or an aquarium base, which is a genuine use for whatever is left in the bag. Cleaning is a rinse in a 1 to 1 water and vinegar mix, dried fully before it goes back.
