Caked white powder with fresh granules pouring from a metal chute in a dark lab setting.

Photorealistic close-up of a caked powder mound receiving a stream of new granules from a worn metal chute. The dark background makes the texture, crystal size differences, and agglomerated lumps clearly visible, highlighting how local moisture or storage pressure can turn free-flowing material into compact clusters. Suitable for articles on powder caking, flowability, and bulk solids troubleshooting.
