Can these bowls withstand boiling water temperatures for a long period of Time?

I use the middle bowl in my crock pot as a double boiler for steel cut oats. I put water in the crock pot between the bowl and crock pot. Plus there is liquid in the bowl. I have no problems using it this way. The minimum amount of time to cook this way is 4 hours.

They are dishwasher and microwave safe. They do get very hot in the microwave for 5 minutes, but I wouldn't push it past those minutes. But, yes I love these bowls.

They are fairly durable and hard plastic, I have not tried to use them on something that is currently hot but I am pretty sure as long as you don't let it just sit there then you should be fine.

I'll try to answer. They are essentially like the Pyrex Mixing Bowls, etc. that you were used to. They can handle hot liquids. I would say you can microwave them better than plastic left over bowls, especially if you've some type of tomato paste in them which would stain plastic. They are not too heavy. They are lighter weight for their size than the Pyrex bowls. I'm guessing 3/16" thick. I liked them for their lightweight.

Yes, but don't pour hot water directly into them. Fill them with cool tap water, then heat in a microwave oven to minimize the risk of cracking due to sudden thermal expansion. The same goes for cooling... Wash them only after they have cooled, and don't wash in hot water when they are cold. (I learned all this the hard way.)

I bought mine for use in a commercial kitchen. They stay cool and do not overheat. After repeated use daily for almost a year, they look just the same. I have these bowls in red. I highly recommend them

The bowls dissipate heat very well but you still need to use a pot holder. They are of a thinner variety/bowl

The plastic is tough enough that I am sure you could put them in a pot of simmering water. I just have never done it that way and thus do not know how long you would want to leave them in. I would not boil them though.

These bowls are meant to be used for salads and soup. They are not Pyrex. A little light microwaving, OK. Boiling, no I don't think so. Find some Pyrex bowls for that.

The bowls have a non-skid material around the outside bottom so I don't think they would work as a double boiler. The material is probably silicone as the description says they can be used in an oven. The boiling water for a double boiler shouldn't hurt the non-skid material, it just wouldn't transfer heat very well. As far as freezing goes that should be OK and the non-skid material should help keep the bowl cold.

These bowls are NOT microwavable safe. We microwaved things in them and the bottom became warped. almost melted. The bowls are still useable, but I will not microwave them again.

If you heat something too long/too hot it would affect the temperature of the bowl, but if you are careful to remove it mostly by touching the lip of the bowl, you should be okay. They are a thinner microwave plastic than I prefer.

I use them daily and never worry about the temperature of the glass before I pour boiling water in it. I am very careful though when I wash my wine glasses because I know if the water is a bit too hot they will crack. I can't say that if you have them in the freezer before filling them with boiling water, that they won't crack, but under normal room temperature ranges or even slightly below, I would feel very comfortable. They are extremely sturdy.

Per other comments, they are fairly fragile if they are bumped or dropped, true. Some items can bounce and survive but these will chip or shatter into pieces. Note: I stack mine in the cabinet but keep a folded paper towel or two between each bowl to prevent any possible chipping. I have had mine 2 yrs or so and all still fine which is a miracle for me!

yes..even at 500 I wouldn't worry about it..I'm a retired french chef and have made 1000s of onion soups in these type of bowls..I was very happy with my purchase of these bowls..none have cracked under high heat..

They can get hot. For example I microwaved broccoli in one of the bowls with a plate set over the top yesterday for 3 minutes and I had to usepot holders to take out out. Just a typical plate of food for a minute or two doesn't get overly hot.

Since Pyrex bowls are safe in ovens (well over 200 degrees) and on a gas range burner over a flame (very hot), using them in a double-boiler (212 degrees maximum for boiling water) should present no problem, though I've never tried it.
