Sandblasting talk

I made a cabinet out of an old chest freezer. Works good for decent sized parts. I lowered my psi down to approx 50 psi? All depends on the severity of rust. Lowering the psi also helped to he able to reuse the media.
Do the parts blast easier when they are blasted in a freezer (lower temperature)???:poke::rofl::rofl::rofl::rofl:
