Question: what gauge of stainless steel is this teapot?
Document: Wanted a product that was Stainless Steel. The kettle is a good quality material.Very  pleased with the price going through amazon. Attractive  workmanship....
Beautiful, heavy, bright finish stainless, teapot with a pleasant hum rather than a shrill whistle - for this reason, glad I bought it.
I find it quite pleasing.So, first off this is a Cuisinart, so it's well made and durable. It's also aesthetically pleasing, nice stainless steel, the spout is attractively curved and the handle is reminiscent of old world craftsmanship.
I really love this kettle. It is a nice quality stainless steel. I like the handle height for ease in filing. The handle does have a seam that you can feel, but it does not detract from the pot and it is a good insulator. This pot has a real spout for easy pouring. I tried one of the short spout pots and it was useless. This is very nice looking and a nice functional and visually appealing addition to the kitchen.
We used this kettle 2 times before a rust spot appeared on the bottom of the inside. We also tried the "Copco Cambridge Stainless-Steel Teakettle" and it rusted after the first use. Apparently it is impossible to find an actual stainless steel stove top kettle which will not rust. I wish at least one or two manufacturers would stop outsourcing to China. It is getting really hard to find quality products anymore. Tea kettles should not be disposable.
It is a very nice looking teapot. But is does not whistle. I wish it did. I always forget that it is on.
Very disappointed when my daughter called and said it didn't whistle.I will be buying another teapot this weekend to replace it.
I love my new teapot. It is so easy to clean, makes a wonderful sound instead of a harsh whistle. Water heats up very quickly. Do not hesitate buying this one
I think this is a good product, but might need more attention in use and care. Keep the flame lower than you normally would. The heat conductivity is fast and permanent discoloration of the sides of the kettle can occur if flames lap around. Don't use abrasive cleaners or brushes because they will ruin the shine of the steel.
I can actually hear it quite well while watching TV in the other room. I actually prefer this sound over the tiny whistling noise we've all gotten use to in previous teapots over the years. Love this teapot!
Answer: The first number in 18/10 stainless steel refers to the percentage of the alloy that is made up of chromium.  In order to be considered stainless steel at all, that number must be at least 10.5%.  A higher value of chromium means that the protective layer will be thicker and will repair itself more quickly if damaged.  Therefore, 18/10 stainless steel has a high level of chromium, and will be more resistant to staining and corrosion.The second number in 18/10 stainless steel refers to the percentage of nickel in the cookware.  Although 18/8 also indicates high quality stainless steel cookware, the higher both numbers are, the better the cookware.above information quoted from: http://www.only-cookware.com/what_is_18_10_stainless_steel_cookware.htmlAlso, the whistle does work, but you really have to boil the water excessively.  not a problem for me.  I just listen for the water and turn off the heat when it is ready.  We are very happy with our tea pot.  We use it multiple times a day and it is holding up well.
