Granulated Cork — also known as cork grain — is a lightweight, eco-conscious natural material composed of ground cork bark, recycled cork stoppers, and cork off-cuts, repurposed from cork waste that would otherwise go to landfill. The fine 0.5mm–1mm grain size and ultra-low density of 50–60 kg/m³ make this the preferred grade for applications requiring the finest, lightest cork grain available — particularly film, theatre, and stage set design, where the smaller particle size more convincingly simulates fine sand, soil, and natural terrain textures. In garden soil, granulated cork improves aeration and moisture retention to promote healthy plant growth without synthetic additives. In industrial settings, the fine grain is well suited for use as fillers, insulators, and component materials where a lower density and smaller particle size are advantageous. Each cubic foot contains approximately 8 pounds of cork grain and would fit a 12in × 12in × 12in carton — note that cork grain may be a mix of compressed and loose grain, and orders of more than one cubic foot may be bulk packed into a single carton. Perfect for film and theatre set design, stage prop making, gardening and horticulture, industrial components and fillers, oil spill absorption, and any application requiring the finest, lightest natural granular cork material available.
