had an opportunity to sandblast some glass with the sandblaster at Pratt Glass in Seattle, WA. There was a lot of pressure as this blaster rents for something like $50 an hour. I couldn’t decide what to do. BT, being a gamer, suggested a Portal logo. I tired to sandblast at different layers for this piece, but it being my fist sandblasting and me being impatient, it didn’t turn out that way.
