OK. Lots of people have trouble sorting these out, and for those who get strayed: 1. Nalgene is a brand name, not a type of bottle or a kind of plastic. 2. Nalgene bottles come in Polyethylene (the classic white translucent ones). 3. Nalgene bottles come in Polycarbonate AKA Lexan (the new rigid ones: transparent, first in smoke colour now in many colours). ========== 4. I think the original Q was about the old white PE bottles (getting harder to find) not the rigid Lexan ones. I do not know if they are affected by boiling, but I certainly doubt the new type PC/Lexan one are. 5. I have 10-15 yr old PE bottles, some of which were frozen almost daily for years on end. I don't notice the taste, and because they are a bit flexible I felt better about freezing them. I never worried about splitting them with ice expansion. It is only recently that one split in the freezer, after being filled under a block of ice already inside, which was then pushed against the top end, and pushe dthrough it by the expansion. 6. I sometimes freeze the PC/Lexan bottles, but with cubes as a starter to limit the expansion of a single block freezing. If I just put water in to freeze, I put only a little water in to start them off, and on a slant so expansion will push up the sides, and not straight outward. 7. I cannot see how the PC/Lexan bottles could resist the pressures of a full bottle of water freezing and expanding. I have burst all kinds of things over the years. 8. Just so you know, I live on ice water the way some people live on coffee. GaryJ >>>I would say no.
