Question: Is the glass all one piece? Do they use silicone inside like some other products to prevent leaks?
Document: You can prabably get one alot cheaper that's not glass. But I find this very elegant looking, almost like a piece of art on my kitchen counter. However, after a few use, you will need to use a soft sponge and scub the hard cloudy water mark off the glass and the silver part in the middle. But it will shine as new. heats water super fast. And I like to look at the process :)
This kettle is just as advertised in almost every way. It boils water fast. It looks good. It's easy to use. It's a great product in all respects except for one:  it makes my tea taste like plastic. Why? The materials that contact the water are all glass and metal, however the inside of the lid is plastic. This heats up as steam rises and imparts the flavor to the water.
Outgassing is terrible! The &#34;silicone&#34; (gawd only knows what it really is) ring inside of the glass is in constant contact with the water. The on/off auto switch has not lasted longer than 8 months on both of the kettles that we bought. It does heat the water rapidly, that is the best thing I can say about it.
The silver piece on the lid to the kettle fell off in a matter of 12 months- the plastic piece to the blue turn off light on the handle broke off in a matter of weeks, and the chrom on teh handle is pealing off in a matter of 12 months. I liked that it was glass so calcium was less likely to develope on the inside - however the product is not manufactured well.I would not buy this product again...it easily fell apart on me.
I bought this glass kettle at Bed, Bath and Beyond. It looked very nice in the box. I took it home, opened the box, took out the kettle, and looked inside. There I found a corn-kernel sized piece of SILICON GLUE -- a small ball of it sitting in the pot! I kid you not! The kettle also literally stunk of silicon glue odor. The smell automatically raised red flags.
Buyer's remorse: I regret I must count myself among the legions of reviewers that report a pretty distinct odor coming from this kettle. The unit works very well and looks very nice, but it undeniably does smell a bit strange. I think the odor is like that from silicone caulking that hasn't dried yet - which would make sense given the silicone seal this thing uses between the glass and the heating element. I am hoping the silicone will cure fully over time and stop smelling.
At the time I really liked the style of this Kettle,but within a week I saw a leak through the seal which looks to be silicone,why on earth they would use a compound like this in a heated enviroment is beyond me.I took the kettle back and got a replacement now after putting up with the smell from the silicone the centre heating element is rusting,which is supposed to be Stainless! and the lid hinge broke, absolutely pathetic.
This kettle works like a charm and is very easy to keep clean, however it spoils the smell and taste of the tea. There is some kind of rubber or silicone at the base of  the kettle, around the heating element. No matter what I tried, (vinegar, lemon juice, baking soda) I can't get rid of it. I always use filtered water, so it's not the water. I'm very disappointed, because it otherwise worked wonderfully and was easy to clean.
Have had this kettle for 1 yr 11 months and it is still going strong. We use it at least once a day, normally 2 or three times a day. The only problem we have had is the plastic "polished chrome" top came off the lid and had to glue it back on. In addition, the top doesn't look very polished anymore, more like a piece of silver plastic with water stains.
I purchased this exact item through bed bath and beyond. I had no issues, loved it. I had it for a few years until my son decided to place it in the freezer with water. My only reason for not giving this 5 stars....the inside heating element did not stay shiny. For such an attractive piece, I would prefer for it look pristine at all times.
Answer: Yes there is a silicone seal between the glass and the heating element.The water touches the seal
