Query: Inside Finish Flakes Off Into Your Water

We bought this tea kettle, and absolutely loved it. Unfortunately, after about a year of what was frankly not very much use, the finish on the inside of the kettle began to flake off into the water. We eventually had to throw it away because the water was filled with gray flakes of whatever the finish is made of. Worked great, except for the part where we were concerned it could be poisoning us.
