That's the porcelain. Your normals are flipped. We have quite a few threads of frantic people trying to figure out what this is .
Press Shift+1. This displays the direction of your normals.
select all the points of a patch who's line is pointing inwards (your 5 point patches have this problem). Press 'f'. This should solve it. It may look a bit weird still after you do this to all of them, but once you close the project and reopen it, it should be fixed.
It's really coming together. I like it a lot.
Oops... you already figured this out. sorry for being repetitive.
