Gold powder to melted button ???

[Yggdrasil]

How do the gold molecules arrange themeless as they come out of solution?
Is it a loosely formed cogent of molecules clumped by weak molecular attraction.
Or do they form distinct crystalline structure of variable sizes dependent on the local environment?
Obviously if we could precipitate the largest partial possible it would make our job easier.
An interesting question.

Look at this. On my way to night shift now.

The purer your gold the more it clumps together Acid. That's why it looks larger. Really pure gold powder can look like cinder toffee. Hope that helps.
