What temp will the rings withstand? Think maple syrup making... 225&ordm;

I think you'll be good. These are meant to boil water at 210 and most of these orange/brown rings are silicone rated to at least 230.

The description states the lid and handles are silicone, which can handle direct heat up to 500 degrees. You will not have a problem with a wood stove melting these.

I have used mine for almost a year and often bake veggies with olive oil at 400 or 425. I haven't tried a lot of sugar on things at a high temp though. Slight brown staining on the one I use most. Love these things. Easy cleanup and no sticking.

425 degrees. These are great, have used them in my oven to catch drips and such for years. I do take it out when using self cleaning mode on oven, but that's the only time.

I have seen All Clad pans in 700 degrees for 30 minutes and then thrown into ice water. No problemo! Do not worry about heat with either a All Clad Tri-Ply or a Calphalon Tri-Ply. High end products can with stand about anything that is why they have life time warranties. If you but quality pans they will last a lifetime and then some.

Having just recently received them, I've only used them twice for making dog biscuits at 350 degrees. I would check the manufacturer's website and ask the question. Sorry I couldn't be of more help.

Happy to answer your questions, Steve. I use them in the freezer all the time but don't drop them! They'll break pretty easily if frozen (especially when filled up with frozen goodies). You didn't ask but I'll offer that I'm very careful when heating something up with these in the microwave. Defrosting, yes; warming, sure; getting something pretty darn hot? I've done it successfully and nothing's melted yet, but I'm cautious.

None that I am aware of. They are good quality and I have been using them for over a year now, including Canadian winter days where the bbq is heating up from dead cold to 400 degF+. Metal has maintained shape and strength, just discoloured as any stainless exposed to high heat will.

I didn't research concerning what temp it will endure in the oven. One person said 400 degrees. I used it as candy and fondant molds and they worked well.

They can definitely withstand 500 degrees. They are cast iron and nearly indestructible. The only thing that survived when my house burned was my cast iron pans. They survived a heat that melted or warped everything else made of metal. After sitting the ashes and rain for a couple of weeks, I rescued them, scrubbed off the rust, reseasoned and reused them for another 20 years. Just don't put a hot pan under cold water. It will crack. If fact avoid water, detergent and scrubbing as much as possible to build up a non-stick coating. I have had great results with this method: I wipe the pan out with a clean damp cloth, put in a dab of coconut oil (Avoid olive or other oils/fats with a low smoking point for seasoning the pan.) and sit it back into a hot oven or on a low burner until it is completely dry and the oil has melted. I then use a paper towel to spread the oil and remove any excess then put it back in a (preferably warm) oven. Over time a layer of carbonized oil will built up on the surface of the pan making it nearly non-stick. Scrubbing will remove this coating and it will take a while to build it back up.

I think they can withstand heat; just not from cold to hot. I think most glass is like that.

They can withstand high temps.. If you're baking, it's definitely not going to hurt it! These are used for baking, so 350-425 this will be fine. I'm guessing it can hold up for higher temps, because they have silicon oven mitts. You can probably google a more accurate answer, but I'm 99% sure that this product will not melt in your oven when baking!! :) hope this helps you!

I can't answer that question for you. I didn't use the rings in that manner so I don't know. Sorry.

I think they are made of polypropylene. The hottest liquid I've used them for is very hot tap water (about 115 degreesF); never tried anything hotter. But they are VERY thin so I wouldn't try anything hot enough to burn me.

We got to +15 here once and thought we were going to freeze to death! Anyway, I have not tried them that cold, I suspect they'll work just fine since most electronic things like that are good down to -40. We used to live in Edmonton, AB, it hit -47 (without windchill) once, we decided to move.

I am sorry I don't know how much heat they will tolerate. I use mine in a toaster oven, straight on the rack and put hot dog, etc on top of them and bake. I like mine because I can wash them in the dishwasher, cut on them and they seem to hold up very well.

I have silicone mats for baking that are safe to 500F in the oven, so if these are indeed silicone I don't think the heat would bother them. It's possible that the glue keeping the silicone attached could come loose, though.
