(OP)
can some one tell me why metal turns white when it is sand blasted? - I was just curious since I was quite amazed to see it.

RE: sand blasting
Metal shot for blasting will tend to produce a light gray or silver looking color because of the reflection of light off the roughened metal surface. If glass bead, walnut shells, or dry ice is used as a medium for blasting, you will tend to develop more of a matte surface finish that is not really white metal.

The sharper the grit, the whiter the surface. It is not a function of grit residue. You get the same effect blasting with SiC or slag which are black.
