I think I wrecked my tea kettle. I went away and left it on the stove for a couple hours the other night, and when I came back, it was blazing hot and the bottom was all poofed out. I let it cool down, and it looked all right, but now I realize that the aluminum core of the bottom has come unstuck from the stainless outsides.
Yesterday morning I put it on the stove, and it groaned, and the bottom bulged out in a very ominous way when I turned the stove on. I was afraid there was air trapped in the delaminated base of the kettle, and thought I'd better not use it like that in case it explodes. This morning, I got out my drill and bored a tiny hole in the bottom of the kettle, thinking that would at least keep it from blowing up, right? Well that may be so, but I'm too scared to find out. If all it does it go POW and BLOING! that's ok, but it's really loud, and how do I know what it's going to do? I'll have to keep an eye out for another at goodwill.
