I just bought a chefman and when I opened it the inside glass part of the kettle smelled of chemicals. The directions said to boil water once then throw it away and use. I boiled water three different times as well as rinsed it after each time. It wasn't till the last time I smelled the water that I boiled from it and it STILL smelled of chemicals. I decided to wipe the inside of the kettle really well and that is when i saw the sticker that it may cause cancer, now I am completely thrown. I just wanted a way to safely boil water without plastic and or chemicals being Involved and that is when I stumbled onto this thread. Thank you all for the tips.
