So...just to maybe try to get this moving (Click to Show Hidden Text)

1. Was it not quartz and albite?  It would make sense that they both form in igneous environments, and they do commonly occur together, for example in plutonic rocks.  
2. If it is that then their name origin would be albus or pure white for albite and twarc or hard for quartz

Okay the quartz part is right, and you're on the right track with the white minerals. To clarify, the quartz are the actual crystals and the second mineral is the one coating the quartz. This specimen was from my coach's collection, so it obviously is something not seen normally.

Is the coating possibly a rock? It looks way too powdery to be a mineral, and it looks nothing like kaolinite.
